evga copper heatsink for 6800gt
 

hey guys,

i have a 6800gt with an nvsilencer on it, just wondering if anyone has tried the evga copper heatsink for 6800gt

http://www.evga.com/products/moreinf...202-F1-EV19-01

was thinking about trying one if it wasnt too expensive, but only price i can get on it is 19$.....for a small copper heatsink. so im just wondering if anyone has tried it and what kind of results it gave. i was also thinking of maybe tryin to throw on the evga 6800u copper heatsink because its a bit larger

I doubt this will be worth changing your silencer for.

how about the ultra

with say...a tornado over it

then yes, definately

but if you go that way, strap your card down ;p

well, im just wondering how you guys think it might perform over the nvsilencer, because the silencer only dropped the temp a few degrees, so the stock cooler does perform rather well

the silencer dropped the temps here about 10° and is WAY more quiet, not something to be neglected in my humble opinion.

I have no idea what kind of temps you will get if you use that evga ultra cooler + tornado but I'm guessing 20° less then the silencer. maybe more, I really don't know

well, im thinking of ordering both the evga 6800gt and 6800u copper heatsinks, ill see how they all compare

The copper heatsink (standard) isn't performing that well, and is very noisy.
I put on my own custom waterblock, and now its performing well @ ultra speed, without any noise.

Stressed temp= 41 max, idle 39 (yeah, that NV40 chip is a real hot stove)

well, i dont have $ for watercooling right now, and i've had this card up to 460/1170 without artifacts, but once it gets too hot, it shut down and i cant finish a benchmark past 437....im tryin to break 13k in 3dmark, and im less than 200points away

did you try running in diagnostic mode, running 3dmark in real time and killing explorer?

How you do that Kristos? And whats the benefit of it?

start - msconfig - general tab - select diagnostic startup - ok - reboot? yes

et voila :) nothing but the bare necessities are running now. a lot of survices turned off aswell.

to get back to normal mode do the same thing but select normal startup instead of diagnostic startup.



-----------------



start your benchmark first but don't run it yet, then:

ctrl+alt+del - processes tab - R click superpi.exe (or whatever benchmark you are running, just using superpi as an example here) - set priority - realtime - R click explorer.exe - end process - ok

run benchmark :)


sometimes you'll also see userinit.exe, if it's there, kill it too.



this way less memory will be used.




to get explorer back:

ctrl+alt+del - file - new task (run) - C:\WINDOWS\explorer.exe

offcourse, C is an example, use the corresponding drive or partion letter.

well, i did finally hit my 13k goal without the copper heatsink, although i have the ultra version on order and some zalman ramsinks, i have an 80mm tornado to put as i ordered a 92mm to put on my cpu, and the 80 will move to my vc. but anyway heres the screen, hopefully i can get higher later, i didn think of running it in diagnostic mode as i was rebooting the pc constantly to change things and couldnt be bothered. also, my memory timings arent listed, my ram also would not go above stock timings or fsb (STILL), thats why the cpu is mostly multiplier overclocked, with memory timings of 2-3-2-5 (didn try 11, will later). this was done on a cold night, had the window wide open with a fan blowing air directly to my pc, about 6-7ft away, and the ambient temp detected by the motherboard was 9c



btw i normally use coolbits for overclocking, but i used rivatuner this time to disable the thermal throttling or whatever its called that was recently mentioned in another thread
