air cooling with peltier...

[lightning]

any comment if i put a 85W peltier on my Alpha PAL6035 to cool my PIII750@960? will that be good or worst? i need to know coz this cpu need to be cool down in order to had good performance! what kind of power supply should i give? coz i find out those peltier at leufkentechnologies.com an they didn't mention what kind of power supply do need to...

i have seen an article about how to do it. Water cooling just seems so omuch easier however. Here is an article about to how to do it. Its very bulky!

Err. the page is not loading. it is at www.ocmod.com and is a very comprehesive how to on how to build an air cooler with a pelt. Worth checking out. Sorry for not being able to give a direct link.

NO NO NO, BAD IDEA
air cooling one is not the best idea, it may work but not that well , people that air cool them often get worse results.... rember that you will not only have to cool the cpu but the 80 some odd watts that the peltier puts out. True alphas are good coolers but that may just be to much for them.

You need to use water if you want your peltier to give you results that rea worth the money you spent on the peltier itself

i disagree jay, this is a great idea, if done correctly like the ocmod.com article. It is also safer than water cooling where leaks are a problem. The only problem i had with it was the bulk.

i should elaborate, this is a good idea if done correctly because even with 80 watts more of heat, if you have sufficient airflow in the case, you will not raise the ambient too much, but the air coming onto the cpu is cool, allowing you lower cpu temps, and that is a good thing.

I have an 86w peltier on my PIII 800E with a slot 1 Alhpa cooler. My cpu temps are around 14c at an idle. Its not a bad idea. But you will get a lot of heat being pumped out of the back of your case. Make sure you have sufficient intake and exhaust fans in your case though. Other wise your system temp will rise and so will your cpu!

I'm going to water cooling with this pelt in a few weeks. Main reason being the noise of all the fans as well as I want to get this cpu a lot cooler to try and get above 1008mhz stable!

Good luck to ya.

By the way I'm using a 431w Enermax PowerSupply for the everything. No second PSU for me. So far I dont need it. This Enermax can take anything I throw at it so far!

sorry about posting another same question again due to the server problem! but thank for all your advise! huh....i think i should go for water too! but i cost a little bit more then air cooling!

 

[lightning]

any good suggestion for water cooling? home made or direct kit from store? now in cut cost situation but still need some good cooling for dual PIII-750 cpu!

drats lost my post with the change over...you get that...
To recap briefly, I dont see why you couldn't run the pelt on the outside of the box (only reading about pelts for about a week so I'm no expert), but from the way I see it if the pelt was on the outside of the case it would eliminate all the negatives and keep the positives, i.e condensation around the CPU, additional case temp from the pelt, less noise because require less fans to cool etc...
If you were woried about loss of efficiency you could always use a larger pelt... what do you think?

humm.....sound interesting, but one thing is how we set all those stuff? how we put the peltier outside the case? i also have no deap knowledge on pelteir too!

 

[Kryten]

on second thoughts I'm not so sure it would be anywhere near as efficient, the pelt is taking the heat directly out of the CPU on the outside of the case it would only be able to draw heat out of the water cooling system....

There are two issues getting confused here. The first one is putting a peltier between the CPU and an Alpha Pal. The second is making an A/C unit out of a peltier as described at OCMOD. They are completley different things.

I have seen peltiers run well on an Alpha PAL in the old days with 50w peltiers, but I don't know how they would cope now. And your main problem will be your case temperature rising and then cpu rising, and then case temperature some more e.tc. You will need good case cooling.

Water is the best policy

Sorry I only have a short attention span..have I drifted off topic again 8)
