Well Its finally in I have waited so long to water cool and I love it my temps never go above 42 on load and Idle around 31-33. My air temps were 35-40 Idle and up to 62-65 running to instances of Prime 95.


My actual question is this the Mobo I have has a pasive heatsink on the NB that used to get air flow from my CPU fan and now has none. So I go to touch it last night to see how hot it is and i could barly touch it from being so hot. There have been no performance issues everything runs smooth. So should I throw a small fan on that bad boy tll I can water cool it? My mobo is the Asus P5P800. Thanx for your tima yall.
 
If youve got a spare fan lying around then i recommend sticking it on as more of a longevity thing as opposed to a stability thing, dont want your board dying early now do you? j/k, it cant really kill the board but it will most likely shorten its life without a fan.

it might not make that bigger difference overall but if you can without too much trouble its better to for the sake of it. You should get more stability with a fan to push your o/c even higher which is some incentive to get cable-tying as soon as possible :p
 
i would definitley slap a fan on there...but i don't believe in passive nb cooling anymore(unless its a monster hs and you have awesome case airflow)

nb's nowadays are just too damn hot to be run on just a little hs anymore, imho
 
i switched out the stock passive nb heatsink to a larger zalman passive heatsink. using a temperature probe with the case open i was getting 54C between the heatsink fins, about 57C max via software monitor. took off the fan from my stock amd64 cooler and velcroed it next to my Neo 754. about half of the fan on the NB and half on my already hot 9800pro.

probes report max 36C now and the software 38C...

can't even tell i've added the fan over my pump/res/panaflo
 
I don’t know what you’ve got as a waterblock…
But my DDen TDX LGA775 mounting pins are exactly 8cm apart. Finally Intel made a wise mounting decision! Yay!

I used some extra mounting equipment and was able to mount an 80mm fan from my TDX pins, directly over the NB Passive HSK on my DFI LP 875P-T motherboard.

It’s working great! Once I receive my ThermalRight NB HSK, I’ll replace the stock HSK and keep the 8cm fan.

Sorry no pics online atm. But I could take some over the weekend.
-peace
 
Thanx for the mounting Idea I threw an old AMD stok fan on it hung it from the screw from the waterblock..Nice and cool now thanx all...
