Quite a different heat issue

post #1 of 5
Thread Starter 
I built a beast for use at work, cuz we get crappy laptops and I need plenty of power as you can see from my sig.

My problem is the GPUs pump out a huge amount of heat all the time, cuz my 3 GPUs run between 60 or 70% of capacity all the time, but they each run at 87DegC (OCed). So that's three GPUs pumping out a lot of heat into the typical work cubicle.

And is darn not for me, shame we don't allow people to come into work in shorts!!!

I stuck a Noctua NF-P12 120mm fan on the rear of the GPUs vents to help move heat out of the box, and it shifts a lot of heat. Its only a temporary fixture for some testing.

Any ideas how to vent the heat?

I was thinking of attaching a flexible vent tube (or something) to the fan I attached and find a way to route the heat elsewhere, but not sure if I need a fan with higher static pressure to push the heat through the tube.

Well, you cant make heat dissapear.

Attempt to get a "window" cubicle??? You can move heat anywhere you want, but you cannot eliminate it.

Even a phase change unit just moves the heat from its source to another location.

Yes, I think you can use a duct (either one for PC use or just a dryer exhaust duct) to connect to your fan for exhaust. You do not need a fan with high static pressure because the air is not meeting an immediate resistance. Rather, you need to attach another fan at the other end to form a push-pull (ie to increase the pressure differential between the 2 ends of the duct).

If your cubicle is close to a window, perhaps exhaust it out of the window (see the 2nd pic below). If not, perhaps just vent it upward to form a 'chimney'. And, I hope your office is well air-conditioned.

Thanks!

The office has good air conditioning so no issues there. I was thinking about a duct, not sure if anyone had come up with any other solutions.

And, if your cubicle is close to an air conditioning vent, you might even connect a duct from it to feed your PC with nice cool air!
