Found some old pics: TEC Air Chilling

One of my first TEC experiments over 3 years ago. I created a little TEC air conditioner here with a 136w peltier and some large heatsinks. I ducted the cooler air over the CPU. Did it work? Nah. The air was a few degrees colder than ambient but...the hotside of the peltier was much too hot.

This kind of thing could work though these days. With some powerful TECs, a liquid cooled hotside, and pumping chilled water through a large radiator, you could chill the air in a PC pretty darn good. However, its very very inefficient, and your better to just liquid cool the CPU directly.

Live and lern :)

Cool photos! Ahh the good old days....seeing that old Globalwin cooler and FreeSpeed Pro hanging on that slot A brings back some good memories.

BTW....I really gotta get some of my pics up onto the gallery! I have so many neat pics I just gotta find the time to do it.

Yeah, the new gallery is great. I posted a whole ton of old pictures I had today. All 4 revisions of my dual loop chilling system, my first water cooling expirments. Im so glad I took pictures of most of my projects, it's really neat going back to see where I've come from. And to all the newbies with good or bad ideas, I've been there, tried it, and learned by screwing up myself ;)

Look forward to seeing you in the gallery Mike, the new PhotoPost software is GREAT :) FreeSpeed Pro, that was the name...I forgot that :) GlobalWin VOS32, modified with a Swifty copper plate so I could cool the L2 cache as well. Remember those days?

Got 1030mhz out of that 800mhz clock. Remember setting the L2 cache dividor? :)

hehehe...yep:D At first it was a solder job on the PBC of the slot cartridge. And I remember the Abit KA7 mobo being such big news because you could actually change the divisor in the BIOSwithout soldering...oohh...ahhhh.

I'll definitely be gettin some pics up soon:) I can use the pics from those reviews that were never born!

ahh.. I love old stuff like this. Althou i woulda never thought of doin that with the computer I had back in the day ;) It seems awsome now.


Hmm.. we have a slot A 700 at work, might be some fun to toy with.

ahh if i remember right the old 700's were generally pretty good :)

i remember getting an old 500 (the very first revision out!) to 863mhz... it was a beast in its day :)

My 800 was a C revision, which meant it had the 0.18 core instead of the 0.25. I remember it running sooo much cooler than the old 700A core I had at work. Yep, I never did solder for L2 cache, cause my Asus K7V had that built in to BIOS as well :) Yep, my first athlon *le sigh*

The computer I had before that I built in college back in 97, and it was a Pentium 233MMX which had been upgraded countless times. So the 800mhz was a big improvement :)

Funny thing I've been realizing though is just how easy it is to build a computer these days. I've been screwing with a lot of older hardware from like the mid-90s. Back when plug and play was a new concept. Geez, you know you take for granted that you plug a HD or a CD-Rom or a sound-card in and its just going to work. No way. There really is a 'lost art' here. I was setting IRQ jumpers on an ISA card, and I started remembering just how much pain was involved back in the day. I remember it taking 2 weeks to get my first 4x CD-Rom to work properly in a 386 machine, you know...back when sound cards had an IDE channel for some crazy bizarre reason. (Yeah, I know...the 'multimedia kit' days).

And I haven't even mentioned OSes. At least i know that when i get the hardware straightened out on these old boxes that Windows 2000 will make sense of it all really. But remember battling Windows 95? Or NT4. Or even worse...3.1. Ouch. I tried to do networking and internet access in Win3.1 once. That shit was hard, let me tell you. There might be better software to do that now, but I remember having to set TCP stack parameters by hand and shit. Damn.
