Lets Get Extreme! PhysX watercooling with Pics !

By the way, if you want massive power at 20 dBa. Here is how to do it:

1 - Buy the Thermaltake 1200 Toughpower (which absolutely no one would ever need but does include only one fairly quiet 140 mm YL fan).
2 - Carefully crack the unit open.
3 - Remove the stock fan and replace it with this: http://www.performance-pcs.com/catal...ducts_id=20771
4 - Now undervolt the fan to 7 volts before it reaches the PCB
5 - Remove the crap plastic shorting strips, cut them and then glue two patches to the side to prevent shorts (if not removed, your PSU will whine over 700 ~ 800 watts load)
5 - Rescrew the fan to the top and reinstall carefully. While your at it, put some heatshrink on the wires coming out of the Toughpower.
6 - Now listen to that monster go at only 17 ~ 20 dBa! (of course your exhaust temps will now run 49 deg C instead of 44 at 350 watts load, but still not bad)

Caveat: I would only do this mod though if you plan on drawing 700 watts or less from the Toughpower. If your really are in that 0.1% of people that has Quad SLI, 10 RAID 0 arrays and five water loops, just leave in the stock fan. It is not that loud, ~30 dBa.

Hey guys,
Not trying to turn this into a PhysX forum but some of you were asking about how it might pan out down the road. Take a read here: http://www.anandtech.com/video/showdoc.aspx?i=3048

Fairly good article with some info on Havok FX and GPGPU.

Enjoy,

Death to 40mm fans.
Get them before they get you. They're scheming to fry your gpu.

Jay,
If you're getting an order from PerfPC, get them to throw in some of the black three pin fan plugs they sell from AC Ryan.
Finishes off your black sleeving nicely.

Yeah, when I first started overclocking about six/seven years ago, I always tried for high speed and low temps and damn the noise. And now, well, I have a fiancee, and she would like to have a baby some day. And it's hard to practice for projects like that if you have a damn whining sound in your head during such times.

Okay, seriously, my rig is primarily watercooled for absolute quiet and I never leave a 40 mm fan anywhere if I can help it. Once I got the Q6600, I had it up to 3.380 for about an hour or two and then I dialed it back down to 3.2, where it now comfortably rests. It runs a little bit high at 44 deg C, but then my rig is usually running about 20 ~ 23 dBa when the HDs dont seek too much.

40mm packing up and frying gpu cost me three vid cards last year. I had to buy replacements in each case to keep the box running over the weeks involved in warranty claims.
Now they're thousand dollar cards, WC is cheap insurance against 40 mm attack, imho. Add in a 680i and it's a no-brainer.

(just dont let Ageia know that I reverse engineered their drivers).

what do u mean by "reverse engineering" their drivers?

Hey Monkeywoman (Great name by the way),
All software properties of Ageia are protected by copyright law and in the US you can patent software as well as hardware. While having no special desire for James Bond type secrecy, I can say that it would not be a good idea for me to go into details about to how reverse engineer their drivers (not trying to blow you off, I just dont want to be sued). If you are an adequate programmer or engineer and are decent at coding, their SDK is available for free at their website and reveals much about how the PhysX card works. There are also such things as bus analyzers, interactive disassemblers and decompilers that you may want to check out if you have similar interests.

ROFL... thats great!! Have you noticed any performance increase?? If you said this already I guess I can't read, lol.

Yes, if you overclock the PPU like a normal processing unit, it will go about 12% higher and if you make adjustments to the drivers you can get about 40% more performance in certain situations. What this translates into for the average GRAW player is that instead of a slight 3-7 FPS slowdown when using the PhysX card (like when throwing a grenade under a car), you actually get just about zero FPS loss. And in certain situations where the API is more closely related to the frame rate, you obviously have more FPS (like Cellfactor).
