radical GPU cooling

Hi,

I think I just invented a new consept for radical GPU cooling. I have been a hobbyist airbrush painter (painting stuff even I don't want to put on wall) for a few years and now I was looking the compressor, like the monkey looked a bone in Space Odyssey 2001, then it hit me, heureka. I will use some duct tape, aim the air hose directly to the GPU fan and see how it goes. I haven't tried this yet. What could go wrong? Sure this makes some noise, but, airflow could be cranked up to 6 bars, so this should cool that thing quite radically.

Patent not pending. :)

I guess You're going to see slightly lower temps & slightly higher clock speeds..but I wuoldn't expect too much.. air is air & it would be far from watercooling + with quite some extra noise =)

Had a simillar idea, to make a shrowd out of thick paper & add server grade fan (120-140mm) spining 2-3kRMP just to see how that goes, but when I heard those fans I changed my plans =DDD..

Nothing can beat inventing. :D

Well, I need to do something, probably buy whole new PC. Around august, so this compressor trick could work in the mean time. I try this today, if this works so that temps stays somewhere below 70 C, I'm good. Now it's constantly at 85 C limit under load.. I have looked up also a small silent airbrush compressor at around 70 USD, so not bad, if this duct tape concept works.

Okay, did a quick test :)

Temps dropped down to 70 C with airbrush pointing to the GPU fan. Then as a control test, I left the computer case open, pointing it to a open door (a bit chilly day today), temps went to 74 C and stayed there. So the airbrush gave 4 C benefit. Conclusion: I think I'll just leave the case open, pointing it to a open door.. :ugeek:

=DDD You can have a huge fan to blow to Your PC too..- that might cut few degrees more =) or simply get much faster spinning fans on Your case & that will get the same effect =)

Thanks, but nah, although I have one excellent fan for that, I think I settle on this setup for the time being :D

Or maybe when it gets hot out side, then that fan and the fridge would work..

Okay I stop here. :D

Ristoraven,
Original idea. If this works for you... why not.

2x Titan X (freshly tested) with two slot distance from each other and a very well ventilated case go at 62-70C at 60% RPM at a very mild noise (not comparable to watercooling but it's not that bad). Cranking up Titan X fans to 100% (jet noise) reduces temps to 48C. Sick result for air, but the noise drives me crazy.

have You tried to OC with those fans on 100%? =) curious how far that would go, what one could get from such setup =)

1520 MHz on core (no OC memory 3300 - locked in MSI AB, but in precision X 4000 would be the target) + mild OC in voltage to 1.21V. I didn't want to push them higher on air. On water I'd get 150 score easily with crazy low temps. From what I read on overclock - OC for gaming not always gives great results and it's hard to exceed 1500 mhz. Octane makes use about 85% of Titan X power, that is probably why it OCs so easily.
