What on earth is that MASSIVE silver thing in there?!
You must be new here, or at least to this thread. HippieTech likes giant heatsinks and despises temps >50C. He thinks they give him cancer or some shit like that.

Lol yeah quite new. I thought air cooling was a thing of the past? Why not just get an H80i or something?

Sweet rig. Where did you get the aluminum extrusions?  Is it 80/20?

Ok, time for a bit of showing off my rig:



5x Sapphire Radeon 7970
3750kHash/sec Litecoin
and blowing the heat right out of the window!

Finally someone used the brains to have the rig pointing upwards, easing the heated air flow!!!

Well done, sir!

What if he just set it on its side? Smiley

Very clean rig.  Nicely done.

Not to nitpick, but wouldn't it work more efficiently to rotate it 180 degrees and reverse the flow of the two large fans to compliment the exhaust of your video cards, rather than push against them?

That would work well if the cards were unidirectional in their exhaust, like reference cards. Those cards pictured exhaust heat out of the front of them and the back. With the front less than 6" from the solid counter they're sitting on and some even more obscured by the PSU it is probably hindering their cooling ability. Try laying it horizontally, moving the PSU out of the way, and see if the temperature changes any. My guess is it makes a large difference.

It was for yesterday.

Today we put 4 on it Smiley

Thanks anyway for your feedback.

Woohaaa!!! That really really good setup!!
It's quite similar to what I have build but your vertical placement approach is FAR BETTER than mine, you can fit a lot more of cards, and natural cooling should be a lot better!!!

I was just planing to build two more rigs, and I think I will do what you did!
excellent idea!

Are you all really sure about the "cooling"? The 7950 blows the hot air towards the BACK of the cards.

So in this rig all the hot air is blowing out downwards to the table and if I see right directly to the PSU. And because hot air rises I think you have the problem, that you

a) blow the hot air out
b) and that the hot air rises up again in the direction of your cards

But maybe I am wrong. At least with my 7950s the air is blowing out to the back.

That was a temporary location. I since then moved it into the garage. I'll try to get a laser temperature meter and take some pics when I can.  Smiley

Thank you very much! Smiley  Yes you're correct, I'm just doing natural cooling. There are no box fans or pancake fans blowing on it.

One thing to note, the power supply fan blows a lot of heat. I've since placed it into an area where it's more open.

The hot air is spread out. Have a look a this http://event.msi.com/vga/twinfrozriii/index.html

So a some hot air is probably pushed towards the back. But if you look at my screenshot of a couple GPUs doing 59C and 66C, I believe it'll be fine. I think the other GPUs with higher temps need a TIM replacement. From reading the newegg.com feedbacks, the Twin Frozr 3 have bad TIM from the manufacturer. Once I get around to getting it replaced, I'm sure I could lower the temps quite a bit.

Nice!!! I like it!
What are the difference when the upper fans turned on or off in temperature?
I was wondering to do that but not sure of the results, as every fan I put in my gear no matter where, it only make it worse.

What on earth is that MASSIVE silver thing in there?!

Thats a lapped Zalman cnps 12x. It was crafted from a Diablo II berzerker axe that will smite ALL who dare impose their hot toxic computer fumes on others ! Tongue

I'll never go w/c because its too risky. Grin When the room is 20c or less.. I'm getting close to w/c temps anyways.. so meh..

3 gpus @1200mhz or better.. 1482 mhash/s .. The 7870's TF III thinks its a triple slot HSF. heh..


I'd like to dedicate this one to Crazyates. Breathe by Pink Floyd -->> http://youtu.be/rOtW2Tnaj_A

where do you get TIM replacements from? which ones should I buy? I have 1 7950 that no matter what I do is always 6 -7 degrees over the other ones, probably that is the case too (sapphire 7950 oc boost) also have another sapphire 7850 with heat problems but it's because one of the fans are acting up Cheesy

Memory thermal pad

Change the paste. Install the heatsink then remove and check see what pattern the TIM leaves behind.

Also check the thermal pads on the memory and vrm chips and make sure they line up and are not sqeezed on too tight. eg.. one of my R7870s and mobo both needed some work that way..

Thanks buddy.

It's about 5-8 degree up/down.

Depends on your place or room. When we close the entrance door, we have to have such fans for the flow.

One of my new rigs - 3x5830 + 3x5850 = 2.2GH/s
And no the Mobile Phone isn't a detonator Cheesy I'm using it to restart the PC if it crashes.








I love your setup! Really old school, and highest ghetto credibility so far!  Wink
