GPU Heat Issues

[Fire$torm]

Nice! That's the best idea I've heard yet. My computers are over an unfinished part of the basement, so it's doable

I might end up doing it sooner then I thought. If I manage to swing it before you I'll post the results here.

As it just happens to be the air return vent is in fact in my room, not sure if it's really helping or not.

In all seriousness the easiest way to find out would be to close or block the vent and give it a couple of hours.

I intend to make the return vent active by using an inline fan unit. I will be setting it up to turn on with the main central air fan probably with a relay powered through a step-down transformer from the C/A power tap. This will avoid stringing wire running 220V/120V half way through the attic.

I had the same problem with my new 6970's. They were running in the high 80's with the fans set at 75%. I threw on some aftermarket heat sinks and fans, made a huge difference, both in the case and the room. I used these:

They're expensive, but well worth it. Dropped my gpu temps down to the mid 60's and they're super quiet, even at 100%. Running DNETC with the stock fans, they sounded like an F-16 ready to be launched off a carrier.

Interesting, my 580 runs with similar fans and keeps the temps in the mid 40s at full load. Wonder how that would help the room temps if I added it to my 5870 as the heat still has to go some where.

You should try it on a 4650HD with just heat pipes hmm not saying I've seen it turn off before but I've seen the card act weird - hits 65c when gaming, no idea what it does when on a GPU project, although sitting at 44c basically idle with a cooling fan on it.

Please note that the CPU’s are going to put off the same amount of heat no matter what heat sink you use. The lower temps mean that the heat is getting out of the system into the air faster. Its not going to change how warm it makes the air in your room.

I’m not arguing that you shouldn’t get better heat sinks because its critical to the systems in our application. It will greatly improve long term performance.

My dad uses an enclosed 42u rack with fans on top he has it mounted on his back porch. I would say this is the worst thing you could ever do but it works. I am not sure how it doesn’t crash everything I know about computers tells me that it would have moisture issues when it rains and heat issues in the middle of Aug. It’s been 3-4 years and he has never had either of these issues. It is screen enclosed and 7-8 feet from the nearest outside wall. I would not tell anyone to do this as I’ve had computers crash in my garage from the moisture. Maybe its that his computers run so hot that the condensation is to thin to effect anything?

Please remember this summer that ever 1000W of computer will take about 500-700w to cool.
