Thermalright heatpipe madness!!!!!!!!!!

Not only huge drop in temps. HUGE performance too. With all that cooling ability keeping my rig cool as a cucumber, I can safely benchmark without worrying about temps at all. My load temps while running 3DM06 was only 61C during the gfx tests. N here's what I managed to get in 3DM06 with the help of all the fantastic Thermalright goodies. 18044 marks in 3DM06. KING of the LYN 3DM06 rankings.

Some really good cooling there ianho looks sharp and seems to perform well.

Have a few questions / observations regarding your Viddy cooler. As I am writing an article on modifications I have had to make to make the Accelero S1 regulator sinks fit properly I have noted a few weaknesses and characteristics of different coolers including mine.

The first one I mentioned above and also on a thread to a member on another board using a this cooler.

On that cooler there are no sinks for the regulators only the ram. I see on yours there are more but if you look at the bottom of your stock cooler there is a spot of thermal paste on the far right. That is where your stock cooler provided coverage for those regulators and your cooler kit didn't. I would suggest you do what he did and pick up a ram sink or two and attach them with Arctic Silver Thermal adhesive or equivalent every little bit helps. Second observation I made on this cooler and the other is coverage of the main heatsink and how it draws air effectively from the other sinks mounted on the other components. Here is a piccy of the accelero with the modded regulator sinks and showing the coverage of the main heatsink.




The other thing I noted with mine is backside heat on the card there are coolers specific to this but I added a couple of 120mm arctic cooling fans to the front of the case. In your rig not sure if thats an issue you have more copper and aluminum in there than a machine shop lol. Stock idle for the GPU is 67C .... stock idle for the Accelero with the turbo module is 49C. I have to run more stress tests here but so far I haven't been able to make the core go to more than 52C.

Idle temps attached and the cooler using the stock Sapphire fan assembly for now. Will post up when I receive the turbo kit and finish the article. Interested in your feedback and AWESOME 3dmark6 score .. Cheers

Is this heatsink designed to be used on 8800 series?

[Mac Daddy]

No its not and one of the reasons for my post. The 8800 platform is very strong and I feel there should be a better cooler out there for it ......

I dont understand which part ur talkin about. Can u show a pic of the naked 8800GTX n the part that's not covered by my TR ramsinks? Thanks.


Edit: I just brought out my stock heatsink to have a look. There are 17 spots where the stock white thermal tape covers n all 17 spots r covered with the ramsinks that Thermalright provided with the kit. There are no missed spots. I noticed ur pic with the Accellero is of a 8800GT? Mine is 8800GTX, mebe that's y u thought I missed out on a spot?

On the Accelero its an X1950 just showed it to show the coverage of the main heatsink. On the sinks on your board I think I looked at it wrong it looked like the stock sink covered two regulators on the end of the board. This cooler does look a lot better than the Zalman one. Still might be an idea to put a ramsink on those regulators every little bit helps .. Cheers

No after market coolers for 8800 covers that regulator.

[Max_87]

Zalman has one... not sure if it's sold seperately or included with the copper heatsink.

Woooooo. I've got sum nice blue aluminum Coolermaster chipset sinks. I'll be sure to cover them as soon as I have time to take the cards out from the rig.

Cool thats actually what the other guy did with the Zalman cooler although like I mentioned all it had was the ram sinks nothing else .. your cooler kit is much better but sometimes little things are missed

One of the reasons I am working on a review for my Accelero S1 mod for this Sapphire X1950 pro 512 is because it doesn't work out of the box and it takes 8 cuts with a hacksaw to make the provided regulator sink and heat spreader work. That will be in the article. The second is because this guy did the same mod I did with the same card and left the regulator sinks off his card completely

What kind of attitude is this ?

The installation is real easy, too bad the heatspreaders didn't fit.

The Arctic Cooling Accelero S1 also comes with two heatspreaders for the voltage regulators on your videocard. In my situation I couldn't install the heatspreader on top of the voltage regulators because the heatspreader was too big. You can start hacking away at the heatspreaders to make them fit, but I simply didn't install them at all. In some cases the card get's too hot and crashes but I have no problems whatsoever.
