Temperature woes
 

Ok, I just took the leap into water cooling and my temps are ridiculous. I am using a Danger Den Maze II water block with a black ice radiator with a 200 gph pump (I believe it is a Rese pump) using 3/8 id tubing. My cpu runs about 48 C at idle and 53 C at full load. I do not understand how there is so little difference. I am running a Duron 750 OC to 1000 at 1.85 volts on an Asus A7M266. My temps were 10 degrees lower before I switched to the new 1005 beta bios. I thought that the water cooling was doing ok but apparently with the new bios you get more accurate temps. Does anyone know what my problem may be or what I need to do to find out? Thanks.

well, asus mobo's have ludicrous temperature sensors. also, have you fully bled your system? air in the line will seriously hamper performance. Also, do you still have good ventilation in your system?

I have fully bled the system. I am almost positive that there isn't a bubble of water in it. I guess what I am really wondering is why my starting temps are so high. When I start up my computer and go to the bios sensor, it shows 42+ degrees already. It just seems odd that I cannot keep the temps lower when it is idle. It almost seems like the waterblock only works once the temperature hits 48 or so. Then it really won't get much higher no matter how hard I run it. This is a puzzle to me. I do still have good ventilation in my system. several intake and output fans mounted in the case (which I'm hoping to get rid of eventually). Any suggestions would be greatly appreciated.

When I first built my water cooling setup i was getting aprox. the same temps with the onboard temp probe. I have a A7A266 (1005 bios) with a athlon 1.2 oc'd to 1.4 I was pissed. I spent all this money and still high temps. Then someone mentioned that I should get a compu nurse and put the probe right next to the die with a little dab of ASII. The temp on the compu nurse was 32c idle 39 full load and the asus temp probe was reading 47c idle 56c full load with a ambient room temp of 28c. That was a big difference. I don't know how accurate the compu nurse is but I sure as hell don't trust the asus probe.

the rese pumps are crap.

get a mag drive 250 - 350. danner or ehiem.

I forgot to mention something. I also have a magdrive 700 gph pump that I hooked into the system 2 nights ago to see if it would make a difference. Well, it didn't make squat of a difference. Maybe 2 degrees. I'm just hoping that the mobo sensor is way wrong. I'll try a compunurse and see what it says. Does anyone know how accurate the compunurse is?

Another question...how loud should the 700 gph Magdrive pump be? Mine is really loud. I don't believe that there is any air in it but I am wondering if I ruined it earlier. It still pumps water faster than what I have in my system right now, but it is much much much louder.

Thanks

Tighten the Maze. I left mine lose to be safe, but when I tightened it temps kept dropping. Make sure your bolts have the springs compressed about as far as they will go.

It is a well know fact that mobo temp sensors sucks, especially those on Asus mobo's....

I had an A7V... what a pain in the... nevermind that. It was one of the early revisions, so it had the thermosistor on a wire (like compunurse). I would get ridiculous temps until I read a tip that said to plug the thermosistor into the header for the PSU temperature (I don't even know why that was on the mobo). Instant 10-15 degree (F) drop. Hmmmm :P

Asus basically fudges the core temp since they know that the thermosistor in the socket doesn't actually measure the temperature of the core.
