Advice on Watercooling

[Clairvoyant]

Hi

I would like some advice on watercooling my setup.

I cant go above 2.6 on air as the chipset gets to hot on my motherboard.

I have tried AS5, it drops the temp. But still not enought to stay at 2.7 or above.

System

Opty 170 @ 2.6 (will go higher, but motherboard chipset is limiting me)
AN8-Sli Deluxe
HIS X1900 XTX ICEQ3 (no need to cool this realy)

Any help would be great, as Im just getting to confused with all the different bits and bobs you can buy.

Thanx in advance

What is the actual temp of the chipset?

Ive had mine up to 80C without probs.

 

[Clairvoyant]

before AS5 it was over 100c

now about 90c

get a fan blowing over the chipset heatsink, that should drop the temps a bit and hopefully get you to 2.7 stable

Whats the chipset voltage? try touching the hs, it could be a dodgy sensor

 

[Clairvoyant]

It already has, a fan on it

 

[cokecan]

if its a piddly little 40mm fan then i think you'd be better gettin an 80mm fan or somethin bodged somewhere to blow over the heatsink

If it's the stock cooling, it's probably crap. Here is a pic of the underside of my ctock chipset cooler on a DFI NF3. Almost no contact is being made. I replaced it with a Zalman and have an 80mm Panaflo L1A gently wafting air over the sink and the surrounding motherboard bits. Dropped the temps by silly amounts, was cheap and silent.

Thermalright and Swiftech both do great little NB coolers. I wouldnt go for watercooling just for your NB chip.

The chipset never goes above 55C on my A8N SLI Delux and i cant get my 3700SD over 2.7 stable and thats at 1.55V through the CPU.

Im now looking to replace my sock cooler (northbrige) it is the new version.

With this

Thermalright HR-05 Northbridge Heatsink (HS-026-TR)

looking to replace my sock cooler

Are you sure about that

 

[Clairvoyant]

Yeah get a 80mm fan on it, and bobs your best mate.

Is the stock cooler held in place by pins through the mobbo on that mobbo?

If so go to a hardware store and pick up some small and short nuts and bolts that will fit through the holes on you mobbo/sink. Is some of the red fibre washers you got with your case to insulate the nuts/bolts from the mobbo and tighten them down evenly. not too tight though or you twonk it, but tight enough to make sure there is a GOOD contact with a decent amount of clamping pressure. Should make a heck of a difference. For best results (and if it will fit your mobbo) buy a zalmin NB heatsink AND the nuts and bolts, then stick a fan over the heatsink and you'll have no more toasty NB problems, ever!

I have installed Thermalright HR-05 Northbridge Heatsink (HS-026-TR) & AcoustiFan C-Series Ultra Quiet 80mm Fan - 3 pin (FG-006-AF)

Clocked it to 2.7 and chipset temps are still over 100c. So its gotta be a faulty sensor.
