I also have my radiator blowing it's hot air DIRECTLY at the vrm fan, so take that into account. I really have no other place to put the radiator since the H70's tube is so short.

So I ran furmark, and the temps were actually as bad as if I ran the VRMs bare, so reaching around mid to high 80s. Looking closer at the sink I found that the pads weren't thick enough so the vrm sink was barely making contact. So if you plan on getting this vrm sink you might have to get some seperate pads to stick on the vrms. I'm planning on getting some extra thermal pads soon, so I will update with my results when I get them.

i was just using evga oc scanner and when testing for artifacts they showed up stight away. when i did the benchmark and let that finish i used the artifact finder again and none.
it seems to be when my gpu reaches 40c it wont artifact but below (30c while watching movies) it starts straight away.

anyone else had this problem

Im thinking about doing this but first of all i have a couple of questions before i do so biggrin.gif
If i in a HAF 932 advanced case want to mount two Antec KÜHLER H2O 620 in the top would the tubes be long enough to reach two 7970's in a Gigabyte Z77 ud3h motherboard with two Dwood fan brackets?
If so this is a must for me

The 1st card would most Likely reach but the other wont reach. Put one on the top n the other on the rear.

The problem is i use the rear for my H80i D:

put the h80 up top with the top gpu.

will look into that thanks for the help

Seriously considering two 620's and maybe even a H60/H70 if i can pick up one cheap enough for my 7950's. Just installed the second today and I'll be running into quite a bit of cash in two weeks..
I'm stuck between leaving them, 620's or whatever or a custom loop.. I can afford the custom loop but being a uni student the spare cash will help and the custom loop will make the PC harder to move (requiring draining etc)

Hello All,
My rig is an i5 2500k running at 5.02 ghz using a Corsair H100 set to the maximum performance setting. For graphics I run crossfire XFX 7970 DD cards with the dual fan GHOST coolers. I run the video cards at 1040/1575 using Catalyst Control Center with fans set to 100%. I need to run the fans at 100% because the auto and custom fan profiles do not keep the card cool enough to prevent lock ups. I can run the memory of the cards up to 1800 mhz if I use Sapphire Trixx software but I have never been able to get a stable GPU overclock higher that 1040. I do not think my cards allow voltage tweaking. The performance in crossfire is amazing and it lets me play 3 monitors wide at 5040 x 1050. The noise level however is distracting. I found this forum a while ago and it got me thinking about the mod. I spent a long time comparing costs and results of various liquid coolers and finally decided to buy some refurbished H100's at Frys for $89. I ordered my Trip T brackets and my EK waterblocks copper shim along with some Tuniq TX-4 paste. I eagerly awaited my packages so I could start my mod. I had to slightly modify the brackets because the counter sinks where not deep enough to allow the water block to sit completely flush with the bracket. Note: check the shim, it has a slight burr on one side. The shim should be installed with the burr side towards the graphics card to allow a perfect fit to the water cooler. For cooling the power supply and memory I grabbed some generic 92 mm fans while I was at Frys. I wanted something special but their in store selection was not the greatest for 92 mm. Before I installed the water cooling on the graphics cards I ran a baseline in Furmark. My top card would hit 92C and start to throttle GPU speed because of overheating. My lower card would hit 79C, Both were at 100% fan speed. (Thank goodness for headphones) I put the first card together and installed it. I ran Furmark at various clock speeds and my max temperature was 42C. I could not get the cards to run stable at a higher speed than I could on air but I can run them the same speeds with the H100 at its lowest setting. I then installed the second card. I played around some more and confirmed through gaming and benchmarking that I could go 1150/1700 in some tests but could not get higher than 1040/1600 to work in all my tests. (I use Furmark, 3DMark 11,13,Vantage, AVP, Heaven, Call of Pripyat, RE5, Cinebench and play BF3) I decided to not use Sapphire Trixx anymore because my cards do not seem to get anything out of it. I am now using CCC and at 1040/1575 with my H100's set at low I pass all tests and can play BF3 for hours. My Furmark temps are 38-39C. I am very happy with the results as I now have 3 H100's and a very quiet and fast system. I now need Trip T to make me a custom bracket to hold the 2 side mounted radiators and a cut out in my side panel to match.
