Watercooled Quad-GT owners

Has anyone else had issues with the PWM and no CPU fan?

My system has been solid since I had it, but tonight I swapped the normal HSF for a watercooled setup (only the CPU). Since there is no air going over the PWM, I was expecting higher temps, but once they hit about 85~90C, the system is just locking up.
Putting a fan on it has stopped this, removing it causes the problem to come back.
The shutdown temp set by Abit for the PWM's are 135C, so id assume that they could go higher than the 85/90C im getting without locking up.

I know normal systems wouldn't come across this, but does anyone who has watercooled theirs had anything similar?
What temps are your PMW's guys?

Hmmm this isn't the usual case, as there has been many that has chosen not to actively cool the PWM and reported temps in the 100's of oC. The reported temperature is usually quite accurate too so it's not a case of inaccurate measurements.

Usually I would recommend having some active cooling round there either from the HSF or now in this case an external fan, nothing fancy just some air movement is all that is needed.

The loaded temperatures with depend on your cpu and voltage so it would be great if you could give a few details about your system just to see what we're dealing with here?

Yep you can watercool them like me.

However at load with a Q6600 at 3.4ghz and 1.47v they tend to reach 110c, but Ive left prime95 running for 12hrs and they were stable with that temp along with the rest of the system.

Cheers for the confirmation.
CPU is a 6300@2.7ish (although it can go much higher, I backed off a bit for testing) using 1.3450, so barely over stock voltage.
RAM is OCZ gold stuff.
Fairly straight forward system really. Not in a case, just on my desk.
Ive not seen the temp of the CPU break 40, even overclocked and at load.

Thanks for the links both of you. Thats certainly an option, but I want to figure out why this is locking up first.

Im not sure if its actually the PWMs or the northbridge to be honest. As they are both connected by a heatpipe it could be either.
Going to play a bit more later

Looks like I was just pushing the system too much actually, and wasn't a PWM problem.

I guess a 1.3gighz overclock was pushing it a little bit

Now to get that northbridge water-cooled and get those last few Mhz

Ahh well glad it wasn't the board!
