They never make clear which prime95 test they used. There are 3 torture tests, small fft's. large fft's and blend. The cpu temps during the small fft's test is 2 to 3C higher and much more consistant than the large fft's test, which produces more system heat less cpu heat. If you graph the blend tes...

I don't claim to be an expert. I gave you my opinion. That opinion is based on months of helping new a64 owners at the pcperspective chaintech web site http://forums.pcper.com/forumdisplay.php?f=46. The number one problem they have is insufficient 12v amperage. ( "another one bites the dust" has hap...

My personal rule of thumb, 18amps of 12v, 20 amps for videocard with molex, more for top of the line video, more again for over clocking. These are minimums, buy the most 12v power you can afford. The A64 and modern video cards take most of there power from the 12v rail nowadays. Older spec psu's wi...

You are definatly going for overkill. The stock fans 2 x 120 and 1x 80 are very quiet, and undervolt nicely. There is over 2 sq ft of ventilation on the case. Temps are barely above ambiant. If you are concerned about a particular hot spot on your board, you can position the exhaust of the hard driv...

The K8 is supposed to have 70lbs of force holding the hsf on,so get used to this happening. Your better off releasing the cpu first and removing it intensionally than by accident. Do not twistoff the heatsink as the cpu may twist out and bend some pins. Gotta love the newest technology. Happened to ...

It is not necessary to remove the motherboard to put the XP's on a K8. With the board horizontal, remove the screws and bracket, and the back plate will drop a 1/4" or so. Thead one of the original (or longer 6-32) screws into one back plate hole then pull the plate up, you can then insert one of th...

It seems to be common to A64's maybe because the use so much 12v power. Some times resetting to fail-safe defaults, and reconfiguring helps, some tiimes a flash to a new bios. If those don't help some hot glue or silicone applied to the chokes can stop the resonance. (At your own risk of course). It...

I did some research on this to learn how to place the thermosister on the cpu. One of the sites I found useful (sorry I don't have the site bookmarked) explained it this way. (any errors or distortion are mine) Temperature is the average heat at the point of measurement. The furthur you get from the...

Just another bump in the correction problem. I have a thermister on the side of my cpu that reads of 43.4C and the diode currently reads 70C with a correction of -26 that would indicate my temps(d) = 46C . It was my understanding that a thermistor on the side of the heat spreader would read a minimu...

Thanks for the replies, my cpu is an AMD64 3200+ Newcastle which folds 24 hr/day. As noted it has plenty of oomph for a case fan, but as a cpu fan the restiction takes away much of its air flow. The cpu is moderately over clocked and the fan works well now at 1300rpm, max speed is 1600. At stock spe...

That explains it , thought the 2.0# was a typo. And 70's is uncorrected,44 corrected. I have a chaintech, 70-80 is normal, thats why the correction is so big (-26) Low pressure effects would be balanced by the high pressure side. I doubt much compression, my idle to load difference is @20C, the high...

Don't feel to bad, I had the same problem with my very different result. If it makes you feel better, your corrected cpu temp is higher than mine!! More seriously, the modern hsf (heat pipes?) may have to be so powerful that idle temps approach ambiant. Since we have the same cpu, running at the sam...

Need a 120mm CPU fan
Hi all, I have an XP-120 HS and I need an RPM monitoring fan for it. (I'm unable to use the high temp shutdown on the s754 MB) I have a Vantec Stealth, but would like some more OOmph when I need it but will run fairly quietly when undervolted. Except for Enermax (UC-12FAB-B) 120x25mm Adjustable Fan ...

If you feel you would like the room of the CM Stacker, don't let the price stop you, there is no upgrade. It won't become obsolete, until the mythical BTX is is replaced. It is not the perfect candidate for silent computing with at least 2 sq ft of ventilation, on all six sides, which allows sound t...

Hi, again Ed. I never doubted the accuracy of your report. My temps raise and drop 8C between speedfans 3sec reports when pausing and unpausing folding. Very fast. Either your bios or the dfi monitor is limiting your temp reading to 49C. I'm pretty sure your temperature is greater than 50C and this ...

Your temps are not as wonky as you might think Ed. The very fast changes are to be expected with the in-die diode. Try speed fan graphing, it will probably show much more fluctuation. (MBM has 1 sec resolution, but is no longer supported, but it may work) The dfi software was (my guess) written to h...

Burcakb, I solved for your numbers, and assuming an ambiant of 30C (cpu intake) I came up with the result of -12C. Multiply by 1.1 if top temp refers to 1.9G. Your corrected temp would be 72C. ( A degree more ambiant = 1 less degree correction) Speaking as some one who ran without issue at 79C (-26=...
