CPU not cooling much with water cooling

[hineigger]

With a cheap coolermaster rated for like 1.4gig, I was getting 47C on my 2400xp consistently. WIth a 200mhz overclock. Now at idle on my dangerden maze3 Im getting 41C. Is this right? I thought thered be more to it.....

Im using a radiator but no fan on it because nothings even hot.....

before turning the computer on, make sure that your flow rates are good, and when on check that the radiator is doing its thing good.

it could be that your way of measuring temp for your system isnt very accurat eor responsive. is this the internal or undersocket thermistor?

Oh, well out of all honesty the flow rates arent great at all. But it does flow.....

Not sure where my temp readers are. Hey explain this, since getting my nforce2 board I now have 3 readings.
Motherboard 29C
CPU 28C
Aux 41C

Now Im not stupid, I know the Aux is the CPU because thats the right reading. I know this because cpu was 50C on old board and labeled cpu, and when I put in new board that reading said 50C. WIth water cooling it drops to 41C at idle though IM sure itd rise over real usage. So whats the 28C Im seeing under the cpu?

its most likely a phantom reading... not reading anything.

AUX probably means power supply, i have 3 readings in sandra 2002; board, cpu and then power/aux temp. So what your seeing is a cpu temp of 28 (very nice) board temp of 29 and power temp of 41!

 

[hineigger]

No I doubt that.

Because.... The CPU ran at 47C idle on the old board. I hook in the new board and there is no reason the CPU would now only run at 29C. But the AUX setting says 47C. So Im positive the aux is for the CPU, and the CPU reading is for something else. THeres no reason the CPU would drop 20 degrees C just because I switched boards...

 

[speeduk]

How you know you didnt get a false reading on the other board?

 

[hineigger]

Well let me put it this way.... An athlon 2400+ overclocked to 2.2ghz with a cheap coolermaster designed for MUCH less cpu's probably wont run 29C Or 40C, or even 45C. No way 29C..... 50C makes alot more sense.

Bah! What do i know, i just got home from work, thought id put my 2p in :/

The problem is that the System Metric Buss (SMB) is not totally standardized... on some motherboards the CPU is on channel 1 others are on channel 2. Same with chipsets... some on 1 some on 3.

I've never seen the SMB monitor power supply temperatures, nor am I aware of any power supply equipped with externally accessable temperature sensors.

It is likely you have the right temps, showing up on different channels than you're used to.

For example: On my gigabyte board, the CPU is channel 2, the Chipset is channel 1 and channel 3 is not used. On some of the other boards I've worked with it's been CPU ch1, Chipset ch3, Ram ch2 .... they're all different. (i.e. Check the manufacturer's info...)

If I had to take a guess on yours... I'd say your cPU is on channel 3, your chipset is on channel 1 and channel 2 might be the southbridge or mabye just the air temp in the case. Compare them to the BIOS readings to confirm...
