Well the main reason for a CPU change is a possibly faulty CPU, and I haven't got the cash to replace both CPU and motherboard right now. What I'm wanting is a recommendation from that list of CPU's, or doesn't it really matter?
The majority of overheating problems are rarely caused by the CPU themselves, you quite often find the temperature sensor's gone or is faulty on the board. Either that or the thermal paste has dried out, the fan is clogged with dust or the case has poor ventilation.
That being said, I stand by what I said in the first place; it's effectively pointless replacing it as you're doing a like-for-like.
If I can refer you to this chart: http://www.tomshardw...ew-31696-6.html
- ignore the fact it says "gaming CPU chart list", because the point I'm trying to make is this:
Your 4000 CPU sits in the bottom tier on the AMD side. Now if you're going to replace your processor you may as well do a worthwhile upgrade. The problem you have is all the processors your board supports are not available any longer, and everything from the third tier up on the AMD side is only available on the AM2+ boards, which you don't have.
While I appreciate you do not have the funds now, I do not feel in your case a simple CPU replacement is in your best interests bearing in mind what I've said above re: common overheating scenarios.
