my 2.4c @ 3.4ghz .... PWM climbs up to 60C after 30mins. What should I do?

[RIGorous1]

As the thread reads... I've posted earlier here that I have a watercooling system and my cpu water runs at 44C and no higher @3.4ghz, but the PWM really climbs to the point where winbond HW doctor advises I shut down. So I do. What do you guys suppose I should do? Stick a fat fan right near the capacitors? toward the capcitors or away?

my 1800+ runs @ 60 c on full load and its not OC'd at all and ive had it for 2 years

dont worry about it too much

you know...he has intel system and you have AMD system....

The 2.4C's temp limit is 74c. So I wouldn't worry about it.

thanks all, but I'm talking about the PWM which, if I'm not mistaken, is the capacitors and such on the mobo... the CPU temps are fine (44C), but the PWM is getting really hot.

sorry i thought it was amd i read it fast


yea thats really high then but im no cooling expert ask other people

 

[sman789]

you might need sum air cooling then...my pwm never reaches as high as ur cpu at load

 

[THUGSROOK]

how much vcore are you running?

Taken from Abit's forums:

What is the "PWM temperature"

"PWM" is a circuit on mainboards to convert the voltage level from power supply unit to provide specific voltage to components (ex. Provide CPU with core voltage). We know that CPU could be the hottest component inside a PC system, and we always care about the heat dissipation of it. Actually, the PWM circuit is quite hot too; especially when CPU is at full loading, large current passes through the PWM circuit and was converted to necessary CPU core voltage. Some ABIT boards show "PWM temperature" on BIOS setup page and Windows hardware monitoring tool. This provides users possible hottest temperature inside the PC chassis, and check whether the air conditioning inside the chassis needs to be enhanced or not. When CPU works heavily, the CPU temperature could be around 60 degree C; nevertheless, the PWM temperature may achieve 70 degree C or even higher; depends on the design of thermal convection. The safety limit of the PWM temperature is about 120 degree C, however, we strongly recommend improving the air flow and heat dissipation inside the PC chassis once it rises to 100 degree C.

70*C would be very high....

(full load)
@ 133fsb 1.525v PWM = 38*C
@ 167fsb 1.525v PWM = 39*C
@ 187fsb 1.525v PWM = 40.5*C
@ 190fsb 1.575v PWM = 44.5*C

as you can see PWM temp jumps way up when adding vcore.
i have very good (but quiet) case cooling.
