CPU temperature always high

Specs: Windows XP, Amd Athlon Xp 2400+/1gb ddr 400
Hy. I just changed my motherboard,earlier i had an msi motherboard all was ok my AMD Athlon XP overclocked from 1800+ to 2400+ temperature was fine between 40 and 50 Celsius only on full use it gone up to 50+. The problem is now with the new motherboard i have 80mm fan and an radiator with copper plate under and the temperature never goes under 50 Celsius and goes up to 60+ Celsius. So the question is. Is it o problem working on this high temperature or what can i do to lower the heat ?
P.S The CPU overheated in the past due to technical problems with the fan.

When you changed out your motherboard, or anytime you remove the CPU heat sink you need to completely remove all of the thermal compound from the heat sink and the mating surface on the CPU and properly apply new compound. Follow this like for the individual instructions for your type of CPU:
If you did not replace it or did not do it properly, that is why you are getting warmer than you should expect to (though not overheating, lower is better).

You have to be a little bit crazy to keep you from going insane.

"The CPU overheated in the past due to technical problems with the fan"

The Athlon XP has no thermal protection, if it gets too hot, it will fry. As stated above, the thermal paste & heatsink MUST be installed correctly. Too much paste is as bad as too little or no paste. All you need is a tiny dab about the size of a grain of rice & it should have been spread thinly & evenly over the core.

I'm a little suspicious about your claim that your overclocked an 1800+ (1.53GHz) to 2400+ speed (2.0GHz). That's quite a jump. Assuming the multiplier is locked at 11.5x, it would mean you cranked up the CPU frequency to approx 175MHz? Make sure you maintain a 1:1 ratio. That is critical to good performance with a socket A system. If you're running the RAM frequency faster than the CPU frequency, you're actually hurting performance. RAM timings are important too. I'm sure you had to increase the CPU voltage to be able to run the CPU at that speed, so that's probably where the high temp is coming from. Or it could be your old board reported the temps on the low side or the new board may report temps on the high side. Where are you getting the readings from? And why did you change the board to begin with? The AXP is very outdated & not worth throwing money at.

I only experienced better performance after overclocking. Ichanged the motherboard because the old msi was broken it was struck by lightning which fried the ethernet board,all of the usb-s stopped working,the cpu oveheated 3 times the actual slot got a bit black around from the heat and i got blue screen randomly but mostly when i started an aplication which loaded the cpu like games or bigger programs. That's the reason why i got another motherboard and i got no more problems except CPU heat ,works nice it's an ECS kt-600A. I bought it used cuse as we know it all single core pc-s not worth trowing money cuse this is the old generation and it's twice as expansive than the new generation. So u made me curious i dont really understand all the you wrote above about cpu and ram freq. how can i know those for exactly and find out what ratio is ?
