(I can't find many free photos of what I want to show here. Maybe I could buy some.) See the links behind the model names for nice pictures.

Heatsinks are a mostly practical thing. They usually aren't seen, so visual design is not very important. Exceptions are where part of a device's case is acting as a heatsink and devices assembled by enthusiasts who care how their internals look (including devices that show off their components, like open PC builds and PCs with windows in their case). This post in about the latter: heatsinks for PC components for people who care how their coolers look like.

To be frank, this entry is specifically abnout Zalman heatsinks. I don't know much about the company. Apparently they are Korean with a name that sounds so un-asian that I doubt that the beginnings really were in Korea. But I know that they made several CPU coolers that I like visually. A heatsink needs to fulfil the task of transporting heat from a small surface to a larger surface where other mechanisms then may exchange heated melecules with molecules from even farther evay. Heatsinks can store more heat energy if they have a larger mass. They transport the heat quicker if they are made of materials that are good at that sort of thing, like copper. And they are better at exchanging heat with their envirement if their surface area is larger. If a chip needs to be cooled better, what's mostly done is put a larger heatsink onto it (can take in more energy) or blow more air through it (larger/faster fans). It's relatively cheap to just increase the amount of aluminium and/or plastic and call it a cooler. But making the heatsink larger mainly increases the capacity for how much heat energy it can take in from the die quickly, which is good for eneryg bursts, but not for constant heat absorbtion. And blowing more air through it makes the cooler louder. Zalman took a different applroach around 2000 and was very successful with it in the early 2000s, as it appears to me. They used mainly copper for their heatsinks (even just a copper core used to be a sign for a higher value PC heatsinks before) and they drastically increased the surface area. I don't knwo who invented the style or manufacturing principle of copper sheets intertwined with a copper base to form a fan-like (as in paper fan) structure. But Zalman did this with the most sense for beauty and with a target market of enthusiast PC builders. I couldn't afford any of their products at the time. But I was a fan from the moment I saw a Zalman Flower for the first time.

Under the name flower they released a number of very different, round CPU coolers as well as at least one chipset cooler. The name started in the 90s, where it was used for a ciurcular aluminium CPU cooler for socket 370 (Pentium III, Celeron). I like those, too. But they are impossible to find and I'm not aware of anybody making anything similar with that much metal around the fan. In my perception the copper goodness started with the CNPS 3000 series, a passive CPU cooler. Right there we have a unique design that hasn't been matched by any other manufacturer. If I would find one of these and I could buy it for < 30 €, I would get it for a future retro build. It got a makeover with the CNPS 6000 series later for socket A.

The CNPS 5000 is hardly worth mentioning. It follows the design of the Intel Standard LGA 775 coolers, but without the goal of being cheap. The CNPS 7000 series has a layout simialr to the original Flower, round with fins surrounding the fan blades from all sides except the top. Not a new design, but again, now it was available in beautiful and with a lot of copper (optionally, as it usually was from the CNMPS 5000 onwards) fins.

The CNPS 8000 has less roundness and more boringness and shall be skipped here. Now we're already in a time were CPU cooler mounts were designed similar to the way they are today and so some of these coolers are still usable with modern CPUs without making a custom bracket, for some you would need to make your own or adapt a bracket. But it's a realistic undertaking. In the CNPS 9000 series there are two beautiful models. The CNPS 9500 and the CNPS 9900.

Another unique design (as far as I've seen) is the fanless external water cooler Reserator 1, of which several version exits but all are called Reserator 1. CPU coolers aside, most of Zalman's coolers are designed for PC GPUs, understandably. There is one design that I'd like to point out here. And that's the ZM-80. Here are reviews of the ZM-80C and the ZM-80D. I bought an early version of the ZM-80 (without a fan) because it was the best way to passively cool my GPU back then. I'm not a gamer. But I still believed that I could use a powerful graphics card. And those had started to require active cooling. The two giant and massive metal plates of the ZM-80, connected with a heat pipe, made the graphics card an uncommonly large part. It was the first time that I've seen an extension card block its neighbor slot. There are similar coolers. Thermaltake < a href="https://www.techpowerup.com/review/thermaltake-schooner/">took this design to the extreme (although nowadays there are larger GPU heatsinks).

The more time advances, the more boring Zalman's product range becomes.

A Really Good Laptop

This entry is referencing the entry 'A Really Very Good Laptop'.

What makes a good laptop? Unknowingly I've been asking myself that question for years. I wasn't looking for a definitive answer; I wasn't making notes; But I was trying out different laptops in the hopes to find the one that is right for me. The bost one. I think I've found an answer. And a surprisingly specific one.

Of course a good battery, a good screen, good speakers, and almost every detail about a laptop can be considered important in some situation or another. But when it comes down to it, what I've made out to be most important to me is: A good keyboard (whatever that means), reliability, endurance (also when in a dirty or dusty envirement) and repairability. Although I'm not sure whether the last one should be on that list. When a laptop of mine becomes unusable because something breaks, I tend to replace it because I want to try somethin new, anyway. I've tried an ultrabook for a while. It's fancy, but not important to me. I've tried a powerful one in the style of a Macbook Pro and didn't like that any more than the original. I had a fable for small netbooks for a while, subnotebooks and mini notebooks as well as some modern PDAs, and still think they're all great for certain use cases. But that's not what I want as an everyday laptop. I didn't seriously try gaming notebooks or those cheap, sleek discounter laptops (because why would I?) or a workstation laptop. I don't need that power on the go. When I need that power, I use a stationary machine. After a while, I stopped looking at new laptops or ones that were released in the last 10 years when I had the intention to buy one.

15 Years Or Older

One reason why I focus on older laptops is the keyboard. No new laptop has a keyboard with a good typing experience, keys with 1.5 mm of travel space or more. Newer laptops seem to be designed to be as thin as possible above all. That is a feature with almost no use. But what I consider a good keyboard is sacrificed to design guidelines. There are good business laptops from the 2010s with a Core2 Duo CPU or newer, with 4 or 8 GB of RAM, that are still fast enough for most everyday tasks. That's what I'm using right now and what I've used for a while. The displays are at best what I consider the minimum that allows me to use it for hours from different angles without getting annoyed. But that's good enough. No 4k screen. No reason to play h365 4k video files. So I don't usually notice that that's something that isn't possible with a Core2 Duo and old intel graphics chip anyway. Speakers also tend to be worse in older laptops. But even with modern ones with good speakers, if I want to enjoy the sound or want good bass or mix the profile myself or need volume, I rely on external speakers or headphones anyway. So there's not much of a difference. Batteries don't last as long on older laptops. But they are replacable in seconds and cheap to buy. So that's a plus for older laptops in my view. 15 to 18 year old laptops are thick and heavy compared to what's become normal. But not so much that it would be a problem to cary them all day, fit them in a bag or handle them with two hands and no table.

ThinkPad Legend

So, after hearing so many good things from so many people and having experienced something from every category I've decided to try ThinkPads for myself. Two T400s with different configuration, a T420, then an X201 that I got for free from a nice person who wanted to throw it away simply because of its age. I must admit I got hooked on the ThinkPad fan train for a bit. Those are very very good machines after all. I enjoy the price (used ThinkPads are everywhere and everybody wants to sell loads of them), the build quality, design and that's it. T4xx are good business laptops among quality good business laptops from other manufacturers. There are many, many small things that make uo the ThinkPad experience of the 2010s and earlier. I appreciate the status lights, middle mouse key, track point, separate function and multimedia keys, sleek docking station and easy to open screen cover lock. But they haven't become too important to my daily life. Those details were even more plenty in even older ThinkPads (and comparible laptops, I want to say. But there weren't really many comparible machines.). IBM ThinkPads were also definitely among those with really good keyboards. I like the clickery keys in old laptops better than more modern ones. But I don't consider laptops with CPUs older than Core2 Duos as viable options for everyday machines anymore. Everyday tasks for me include playing videos embedded in web pages and editing raster images as well as vector graphics. Core2 Duos with 4 GB or more RAM work fine. Everything older than that is for retro computing tinkering tasks.

Business Machines With Good Reputation

There are other laptops from the same time to be considered. Those in the business line of HP and Dell. In my experience and personal opinion, HP EliteBooks (as well as some HP Compaq laptops) provide a superior keyboard to those of T400s, but lack some other desireable features that you can trust to find in any old ThinkPad. And Dell Latitudes tend to be reliable and withstand my lifestyle better than ThinkPads from the same period but the keyboard experience varies. Dells come in rugged variants, but more important is that they, according to my experience, handle dust and other dirt better than their competitors. EliteBook keyboards make better use of the available surface area that a 14 or 15 inch screen gives the lower half of the device. The keys are spread out more, arrow keys aren't burried in the rest, insert, home, end and paging keys get their own row to the right. A unique layout, but not stranger than that of other laptop keyboards. A new Latitude keyboard feels much nicer than an EliteBook or ThinkPad keyboard. The keys are springy. When abused for years, they become as good as their competitors, then whimpy and stale. ThinkPad and keys stop working when they meet dust and keys break when cuttings or hard dirt gets under the caps. EliteBook keys just watch and wait to be cleaned. Either are good devices. But considering that both Latitudes and EliteBooks cost 50~70% more than comparible Thinkpads, it's easy to let the choice fall back to the brand with the best reputation: ThinkPad. Surprisingly (to me) that is, in the end, ThinkPads biggest advantage.

A Really Very Good Laptop

Entry created on 2024-09-04 author:steeph (324) cat:#100DaysToOffload (26) cat:Computers (12) cat:Laptops (2) cat:ThinkPads (2) cat:incomplete (29)

This is a continuation of my recent entry about what I think makes a good laptop.

Display And Keyboard Size

I used to think a larger screen would be better, because you could see things better. But when sitting directly in front of the thing, it doesn't really make a difference whether the screen is 12 or 15 inches across. Larger screens tend to be available with higher resolutions. I think my preference for 15 inch laptops come from a time where there was a notable difference in price between laptops with screens with hardly acceptable and good resolution. But I've come to accept smaller-than-HD resolutions even though there are tasks where it really makes a difference. But with 15 year-old laptops, an HD screen doesn't have to make the thing much more expensive. So there are options, even with 12 inch devices.

The other thing is the keyboard (again). A larger device has more room for a more comfortable keyboard. HP makes use of the extra room. Dell didn't, at the time the laptops I'm interested in were made. In mobile workstations with a 15.6 inch screen can have a numblock, a 14 inch one can be less crowded (no half-size keys, spaced out special keys, extra rows). EliteBooks used to do a good job at that up until the 3rd generation. 12.1 inch Thinkpads (or the newer 12.5 inch ones) are a good example for crowded laptop keyboards. Not a bad keyboard. But there just isn't enough space to include and position all the keys one might want to have where one might want to ghave them. The thing is: 14 and 15 inch ThinkPads and Latitudes use the same keyboard layouts as their 12 inch counterparts. That's another plus for EliteBooks if you want a larger than 12 inch device.

So, since I'm on the ThinkPad bandwagon right now, and somebody gave me a ThinkPad X201 from their scrap box, I think that might be what I'm going to use next. I wouldn't have considered a 12 inch device. But, internals aside, it's just as nice to use as a T400, but ligher and taking up less space. I think if I had been introduced to ThinkPads through an X201, X200 or similar, I would have understood the hype much quicker. I will not go much into other manufacturer's counterparts to the ThinkPad X2xx series. But it is worth mentioning that both HP and Dell had similar devices to the X200/X201 both in clamshell and convertable/talet versions and their keyboards aren't worse. The Dell XP2 has a little fan in me. But those might be a topics for another entry.

Old Case With New Oragns, Frankenpads

I don't have anything agains newer hardware. I'm just not ready to give up on laptop keyboards that feel nice to use. The trend of thinner laptops with larger batteries in recent years has been made possible by smaller mainboards with highly integrated CPUs or SoCs. I imagine that the size of modern laptop keyboards is very helpful if one would decide to build a newer PC into an old laptop case. The X201 doesn't seem to be popular for this anymore. Most people seem to preferr newer models for some reason. I would have thought that is one of the most popular devices for Frankenpads, even if it's a bit more work. The keyboard is of the old style, small case still with a lid latch, but there already was an option for a track pad. I have not gathered too much information about doing this myself. But there seems to be enough resources and support in forums to make it a doable project. But you don't even have to. There is a commercial offer for X201s with 10th generation Core i CPU.

I did think about getting a 486 laptop with a really nice keyboard and mod a newer board into that. It would be a nice project. But not as practical as an X201 or similar. After all, the case would be much thicker. Most 486 laptops were about twice as thick. That would make it easier to fit a different board into it and position connectors in the right spots. Most designs wouldn't have room for a trackpad. The availability of replacement parts for ThinkPads is also a good reason to use a ThinkPad for this. But it would be a nice project. Maybe even with an ultraportable electronic typewriter. But for a laptop to buy, the X2100 si the best compromise for many reasons; and you can get it readily built by someone with experience in doing exactly that.

WAMP 2024

Entry created on 2024-09-02 author:steeph (324) cat:#100DaysToOffload (26) cat:Camping (1) cat:Pictures (59) lang:en (178) top:Events:Camps (5) top:Events:Chaos:WAMP (1)

Das WAMP war mal wieder eine tolle Erfahrung dieses Jahr. Ich muss mich bei den Organisierenden dafür bedanken, den Besuchern einen angenehmen Urlaub und gleichzeitig ein Chaos-Event mit Programm zu bieten. Aus der Erfahrung der letzten beiden Jahren wurden Verbesserungen extrahiert und umgesetzt. Die Teilnehmerzahl ist auf etwas über 100 gestiegen. Genau so kann das WAMP meinetwegen bleiben. Ich hätte nichts dagegen, wenn noch ein paar mehr Tickets in Umlauf gebracht würden. Platz ist da. Aber es war dieses Jahr von angenehm stressfreier Größe.

Sicher gäbe es viel zu erzählen. Aber geht doch selbst mal hin, wenn es euch so interessiert. Wer Chaos-Events kennt hat anhand der hier angehängten Fotos schon einen ausreichenden Eindruck. Ich weiß, keine Bildbeschreibungen aktuell. Also zusammenfassend: Viel Platz, wiesen, ein paar Bäume, alles mit viel RGB, in der großen, offenen Holzunterkunft das Hockcenter und der Essensbereich. Ein Vortragszelt, dieses Jahr auch ein Hardware-Hacking-Zelt vom ZLT mit gutem Lötbausatzangebot, beheizter Pool, Sauna, Feuerstelle.

The Silicon Underground Blog

I don't feel like writing because it feels like work right now. I'm in the transition to a new job. Maybe that's why my brain is fuller than last month. But I resolved to post more regularly here now. So I fall back to a simple trick: I use interesting content that somebody else has created and link to it.

There's this blog about 80s and 90s things, with on of its main focus topics being home and business computers from the 80s up until 1999. It's so interesting to learn more about the tech from back then. Like this article about the AMD Athlon. I loved tinkering with PCs at the time. I loved the Athlon and its successors even more than its predecessors. But reading the article is more than fond tinkering and gaming memories for me because I never knew about the legal surrounding and background of technological developments back then. It was slightly pre my first computer magazine subscription.

The Silicon Underground - David L. Farquhar on technology old and new, computer security, and more

There are a lot of posts about computers and its components, model trains, clothing and fashion, but also other things that should work both as entry points into nostalgic reminiscing and a source for interesting but likely now useless facts.
