You should see the fan on the 2 ghz machine! It's like, well, huge. It has little support thingies all over because it doesn't fit on top of the processor. :)</font></td></tr></table><!-- BBCode End -->

SOD: whats good for nasa isn't good for me :-p

Personally i prefer the idea of peltier units with good air cooling. (accually excelent air cooling) also must have a good seal to keep condensation away. But its WAY overkill for anyone but the overclocker try'n to get a PII400 to run at 1ghz

That'd be a good way to start a fire with an old piece of hardware. Take all the fan's off, heatsinks, and silver, and make it run as fast as it stable, stick it in a pile of twigs, open up SETI, and set it's priority to Realtime. Hehehehe...

yeah.. someone should try that. It would be cool- any volunteers? :)

I have a peltiet device (also known as 'thermo-electric units'), which is about 2in x 2in. I've rigged it up to a connector so i can plug it into my box's power supply, but what can I do w/ it? There don't seem to be any heat sinks out there that allow space for such a thing underneath them. I've seen a few that come w/ a small one already on them, but they are fairly expensive and i just got an almost brand new one from a friend for 20 bux earlier this evening.

More on the topic, I'm measuring out where I want to put that side case fan. My 1 IDE and 1 SCSI drives are both positioned pretty much in the middle of the case and above those are the CDROM and CDRW drives. There is a fan near the bottom of the case. Should I place the side fan directly over the hard drives or should it be a bit high, as heat rises?

Yeah Red you would not want to use a cooling system
that is considered industry standard and state of the art.....I forgot that computers are differient than the rest of the electrical devices out there. Stability is what it is used for its byproduct is in fact cooling. Last time I checked the more consistant cooling is the longer a electrical device will remain in a stable state.
If it is left up to ambient temps stability is inconsistant at best. Isn't stability the differience between a 1GHZ proc and a 1.7 GHZ proc? I had a computer science Phd
from AMD tell me that although he was probly wrong.
BTW it is not water cooling humid air is passed through a closed system then cooled.

So what is the cross flow going to do with the front to back air currents Andrew?

SOD: all i got to say is LOL :)

Andy: They make perfectly designed kits for peltiers. I saw them back when i had my celeron 266 and i was trying to get it to run right at 400. I never used one in a PC before though.

Just found a "Peltier Basics" page, Looking over it briefly it dosn't appear to be all that nice with the new AMD's. <!-- BBCode u2 Start --><A class="postbody" HREF="http://www.gibtek.co.uk/watercooling/peltier.html" TARGET="_blank">Look Here</A><!-- BBCode u2 End -->

LOL at what? the only diff between a 1.3ghz proc and a 1.7 ghz proc is its stability at rated power output? Don't laugh to loudly at what you assume. The people who operate computers and the people who build the electronics are miles apart.


consider this:
It is in fact ambient temp stability vs rated device dissapation in watts/@ temp, that is what you are trying to achive. There are problems that arise with multiple device parameters within a single contained enviroment.(your computer case) Since I just rebuilt two Klystron assys.(output "tubes" for television transmitters) and refurbed their cooling system I thought I might give detail at what we learned.


TV engeneers learned a long time ago that individual cooling of components is not effective. The best thing you can do is dissipate the energy/heat evenly
within the case. I have used a thermo-spectra camera to locate <i>hot spots</i> in electronics that is perhaps the best way to do it otherwise find good heat sinks at a electronics supply stote. Most of what you see in computer electronics sucks.
The most important facet of this is the ill-concieved case that computers come in. They have poor circulation, bad rack design, and seem to be a huge dust collector.
I a typical computer you have a Mobo, sound card,
vid card, hard drives, power supply. Trying to target one of the devices in the computer is a waste of time when all of the above create a SUM enviroment
in terms of device disipation. Fans alone are a waste.
Cooling is NOT done to make things cooler. Cooling is a property of a method. Cooling is done to create a composite eviroment so that the ambient
temp is supporting the stability spec.
Why not design a purified, dehumidifed, "air conditioner" to pump cool air into the bottom corner of the case then utilize air flow based on matched fans for air flow in and out of the case. Include HEPA filters ala JohnT at intake and output and adjust the amount of cooled air pumped based on enviroment disipation (group mean) and air flow from the fans. BTW Just 2 fans not 6. Gee perhaps even software to govern the process.....na that would be to much
like real electronics. :-)

The peltier device on that page is exactly the same one I have. It cost me like 45 bux 2 or 3 years ago, so i kinda want to actually *use* my investment in some way! As for the AC idea, I've been trying to figure out how to implement that for a long time. Do they sell really small AC units anywhere that I could adapt for this purpose? The littlest ones I've seen are much too big for this purpose but perhaps I'm not looking in the right places (e.g. somewhere besides HOme Depot?)?

well Andrew I'm doing a search now for components
If I look long enough they will turn up. I looked at that device wonder how much heat it disipates. The cooling unit could be on the floor with a flex tube the length of the tube aids in the consistant delivery of cooled air.
Other factors like huminity, and temp controls could be purchased and soft written to monitor the env. He He *daydreaming* why not have a way to insert O into the cooled air sealed one way air flow like a lung*end day dream*

Went to fry's and found one sink that had a peltier built into it, but it was 50 bux and the sink was aluminum. A salesperson who actually seemed to know what he was talking about said i should just stay with the copper sink i just aquired. I did get one of those silver circuit pens for changing the bridges for my Athlon, some memory sinks, and a new variable speed case fan, which i'll be mounting on the side. I drilled a small hole in the door when I was spraypainting it gold today so i knew where to make the hole, but i think i've miscalculated by about 4 or 5 in (there isnt enough space between the side of the drives and the case door for the fan to fit between in the marked location).

Has anyone else here had experience w/ overclocking the Athlon T-Bird? I've read a lot of places to the extent that if you have really good case cooling, you dont need an insane sink for the CPU when OCing...
