Going below ambient temp?

post #1 of 14
Thread Starter 
I have been told before, and it does make sense, but is it possible to go below ambient temperature with air cooling?

I own a Thermtake Frio and it's great at cooling the cpu, but I already blew up my gigabyte board, and after some research I noticed the coolers that blow down on to the board may help reduce temps and make things safer..


So what I was thinking is, what if I hook up one of the 9000rpm fans I saw? There's one that should be good for 380cfm. Wind chill anyone? Could that go below ambient temp? Thoughts? Opinions?

Unless you're pumping cold air into it (below ambient) It's impossible.

Only if you put it in the fridge.
Whoops, I forgot that doesn't work either.
Go for a phase-change cooling system if you want that. They're cheap, fun, and easy. Only marginally better than something ultra high-end like the CNPS9900, but they make up for it in Kawaii-ness.

No, is the short answer.

It's possible, but not feasibly...


By that I mean if you compress the air cool it to ambient and then let it expand inside your case you would produce sub ambient temps.

There's much better ways to manage that however.

Edit:

About wind chill however, that's referring to the "felt" temperature rather than the actual temperature, to quote wikipedia:

"For inanimate objects, the effect of wind chill is to reduce any warmer objects to the ambient temperature more quickly. It cannot, however, reduce the temperature of these objects below the ambient temperature, no matter how great the wind velocity."

I can imagine however it's possible for moist surfaces to reach sub ambient temps in high wind due to fluctuating air pressure and evaporation in low pressure areas, that's just speculation though.

You could get one of those standing air conditioners and have it blow directly into your intakes... but what's the point?

Omg! I wanted to do that so bad a few months ago until I got a new case and cooler. . That is so funny to me because its exactly what I wanted in my mind. Lol

That AC cooled case is sexy..

So as far as cooling goes, air cooling is only (most of the time) as good as the air around it. But what about protecting my vrm? Like I said I blew a mosfet and Im out of a board for now. I heard that have a down blowing cooler is what amd had in mind, so even though my Frio is keeping my cpu nice and cool..... My system is suffering

Add a vrm heatsink maybe? It would be hard to know what would fit. I'm assuming your current doesn't have a stock vrm heatsink...

I bought a top down cooler for my 2nd rig because its a weak board.
