after market cooling

[dragonfly52277]

Hi; Upon overclocking only 2-3 hundred Mhz, my CPU overheats up to 65C at least.  I purchased this after market cooler: http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=4974358&pagenumber=1&RSort=1&csid=ITD&recordsPerPage=5&body=REVIEWS#CustomerReviewsBlock.  What gives?

What CPU?

I can't find any information on the TDP of that heatsink but it doesn't look like it would do much better than a stock cooler.

[dragonfly52277]

AMD FX-6300 3.5 Ghz CPU.  The cooler was $25.  I have a mini-ATX mobo.  Do the heavier duty coolers fit a mini-ATX mobo/tower?

I had a fan that was sucking the wrong direction.

Hi; I have a micro-ATX mobo and my CPU is an AMD FX-6300 3.5Ghz processor.   I'm looking to buy a cooler for this build in which I can achieve a substantial overclock.  Is it feasible?  I just want a fan/heatsink cooler.  I'm not looking to go water-cooled.  My CPU is a 95W.  My PSU is 650W.   Upon attempting to overclock, Prime95 quickly raises the CPU temperature up past 65C on a mere raise of 200Mhz.  Can you suggest a good cooler?  I'm prepared to spend at least $60-85.

What CPU? You said AMD FX-6300 3.5Ghz.
Most modern CPU designs allow the chip to get close to 90 C and not crash.
Thee is no simple way to extrapolate  a relation with clock, power and temperature. Other that to just says temp goes  up when the other factors go up.

In other r words, a 20% up clock does not mean a 20% temp up.

The CPU may stop before you get to its temp limit. Thee is another reason for the clock speed limit other than  temp.

But that was written some time ago.
