Antec Kuhler 620 cooled Nvidia GTX670 + overclock results (pics inside)

I bought a palit GTX670 and didn't like the stock fan noise from the card. I found it very annoying.

I already had 1 kuhler 620 on my cpu and was happy with the performance. After reading online I decided to cool the GTX670 with another Kuhler 620.

The card with the fan shroud off - it's tiny!

Heatsink off

Kuhler fitted

The cables have been tidied since these pics were taken...

Running fractal fans in a R3 case on both kuhlers in push pull config. The GTX670 kuhler fans are running at full speed.

I'm also running a fractal 140mm fan at full speed under the card to cool the VRM's. I've left the stock heatsink there.

I've seen temps go from 81 Deg C at full tilt on the stock cooler go to 61 Deg C with the kuhler.

Card is also boosting to 1097Mhz without me touching it.

I'll be looking for some better fans soon though as the fractal fans don't push a lot of air at all. Quiet, yes - but I'm sure there are fans just as quiet that push more air. Once I get some better fans I may start to play with overclocking.

Thoughts....

EDIT - - - - -

Overclocking results.... as per Heaven 3.0 thread settings

8% performance increase over stock

Stock

OC to 1247Mhz and mem also oc'd

As far as the card will go. Prob not bad for a reference model.

Temps never got over 63Deg C, I just couldn't get it to run stable at any higher clocks.

Nice! This is something I wish would be developed... I've got the 620 too and would love to get a GPU based version for my 6970. That looks good dude

A bit fiddly to get the cooler mounted on the card. You can get special mounting plates for them etc, but tbh the cable ties more than do a good enough job at holding it in place as can be seen by the temps.

Great Idea! Excellent cost effective cooling solution. Thanks for uploading the photos.

Monkeyspaz5000 · 29 May 2012 at 10:37

If I get another 670 down the line to run SLI I'll be doing the same with that. Only thing is I'll need a case where the HD cages can be removed to fit another Kuhler in. Unless I simply drilled the cages out that are there.

^^ Funny that such a tiny card can beat the 7970 in some performance

.

Im gonna be using this method to cool my 480's soon, but using a bracket, just waiting for it to arrive then I can get mine under water aswell. Need to in this weather !!

Theres a guy in the US makes adapter plates for mounting onto gpu's for about £15 delivered

Monkeyspaz5000 · 29 May 2012 at 10:52

A couple of these instead of a full blown water cooling kit does the job for me. Great price/performance.

Yeah, I saw that. I may still get one, but I wouldn't have been able to wait until it arrived!! Lol

Now that is impressive. Would love to do something like that with one if i got one

psychodil · 29 May 2012 at 11:09

I'm doing the same thing with my 7950. Didn't realise I needed a copper shim for it though

I'm now making up a plate with threaded holes so I can bolt it to the card, Ive not much faith in cable ties.

Great job though, bet its a lovely quiet rig now :cool:

Arctic Cooling have their Hybrid all-in-one GPU water cooling loop out now, however it is $180?!?!?

BigChief · 29 May 2012 at 11:52

Good job well done! nuff said.

Twirlywoos · 29 May 2012 at 12:35

I've seen these mods on Overclock.net, nice to see someone in the UK doing it too. A nice 20 degree drop in temps too. As for fans Scythe GT AP-15's without a question. Or if you were lucky to bag a 120mm 2150 rpm version then that is more preferable as it pushes more air and is only 1db louder.

My only concern would be that the heatsink near the front of the card won't be getting any airflow over it now. Does anyone know what's underneath it?

There's a fan running right underneath that heatsink.

The price of the Accelero Hybrid made me look for cheaper alternatives.

I ordered this today OcUK H²Flo Extreme Liquid Dual Fan CPU Cooler after reading the overclock.net guide. The double thick radiator should give us some cooling oomph.

I have a GTX 580 going to try it on. I thought about ordering the bracket from the US but going to use cable ties although my brother could probably knock up a bracket for me. As I have a reference cooler going to hack that and cut a hole out for the pump to fit in and use the fan for VRM cooling.

Holidays coming up so perfect time for some experimenting.

Ah so there is! - I just took another look at your pictures

spankingtexan · 29 May 2012 at 16:52

I'm interested how you got that 120mm fan on under the graphics card? what method was used there? I see a cable tie, but how was it done?

Mike_P · 29 May 2012 at 18:21

at the first 2 pictures, 300+ quids worth..... looks more like a 30 quid card.

Props on the mod though. :cool:
