GTX 660Ti & Arctic Accelero Hybrid

post #1 of 8
Thread Starter 
I have not found much info as far as installing the Arctic Hybrid cooler on a 660Ti, so I thought that I would post some picture along with some temperature results. The included instructions are rather vague as the Hydro fits many cards. I am merely going to touch on a few things to watch for on the 660Ti.

This is how I placed the heatsinks on the card. I used the provided template with a couple screws to hold it close to center on the GPU. The template is where the pump will actually sit on the card. It is important to use this template as not to have the heatsinks interfere with the pump or it will not fit securely on the GPU.

This is why the template is important as you can see on the left I could not use a heatsink to completely cover the chips due to the fact that I would not have been able to get the pump to seat on the GPU. When installation is complete, these two heatsinks will actually be on the outside of the Hybrid housing so don't be shy about leaving enough clearance between the template and the heatsinks. If you notice in the upper right hand corner by the VGA bracket is a hole where one of the stock NVIDIA hosing screws attaches. The Hybrid housing is held in place only with four screws from the pump. You should have some extra felt pads left over from your installation which can be used on both the VGA bracket and the circuit board so you can install a small bolt and nut for stability purposes.

This is a pic of the heatsinks from above with the housing installed. Not much room to play with so make sure you leave room between the heatsinks and the template (I left about 1/32" and it seemed to work well).

Here is a picture showing the clearance between the heatsinks and the critical components on the main circuit board. I did not use any insulation tape on the circuit board as I felt comfortable with the clearances I had to work with. Unless you are 100% sure of yourself, I would use the insulation tape as the manufacturer recommends. When installing the Hybrid housing and pump to the video card you have a couple sets of adhesive strips and spacers that have to be installed between the board, pump, and backing plate. It would be nice if the adhesive pads and fiber washers had adhesive on both sides to make installation easier but, they do not. What did to ease installation was used some cheap thermal grease to hold the spacers and washers in place on the video card.


As you can see, I have plenty of clearance to add one of the Hybrids to my other 660Ti. I wasn't and still am not for sure where I am going to mount the radiator for the hybrid, so it is just held in place with straps for the time being. (Also note, I need to dust this damn thing...lol).


Here are some preliminary test results between the stock cooled 660Ti and the liquid cooled hybrid 660Ti. I have both cards BIOS's unlocked and used MSI Afterburner with +25 on all settings other than fan speed which is set to auto. For these results I used MSI Kombustor 2.5 and ran the stress test for 15 mins. with SLI enabled. As you can see the stock temp reached a max of 85C where as the Hybrid hit a max of 58C. The results speak for themselves, 80 deg F difference between the two. I have more tests to run after some more overclocking and will post results at that time.

My personal opinion is that the Arctic Accelero Hybrid is well worth the money if you want to overclock your video cards. The lack of clear instructions is a bit of a challenge but easy to over come with a little patience.

Systems Specs:
Crosshair formula-z
Amd 8350 (OC to 4.55 GHz)
16GB Dominator Platinum 2400 MHz
Geforce GTX 660Ti/SLI
Corsair Force SSD 120 GB raid 0
EVGA Nex 1500 Power Supply
Cosmos II case

Do you think that the Stock mosfet heatsink may have been better than what came with the kit? I'm glad you did this, I was looking to do it to my 660ti I just ordered!

IMO the stock mosfet heatsink was better as it is a bigger heatsink. Don't remember the exact issue, but if my mind serves me correctly I could not get the cover on the card as it would not clear the stock heatsink.

Awesome, thanks! I was looking into various cooling options for my 660ti and this was one I was considering. Looks like I may be going with the Asetek 740gf after all. I don't want to cut another shroud, but this go around it looks easier since the 660ti goes use a unisink like the regular 660.

Again, thanks!

Does anyone know if you can expand the loop on the ARCTIC Accelero Hybrid? i.e. cutting off the rad and hose

You could in theory, I had an Asetek 760gc that I removed the gpu block from to make it a double thick cpu cooler and it worked fine. What would you be trying to do with yours?

i was think that if EK keeps dragging their feet on making a full water block for the GTX 770 (Gigabyte 3x oc) i would just get two of these and remove the rads and hook up to two 480 rads with a CPU block in the loop. Thoughts?

PCB is so small.. fan is outside of the pcb... so there is no use for 80 mm fan then?
