Replacing old CPU for new, different socket number

[Deadly Ferret]

I've tried searching but can't find a reliable answer, and don't want to risk buying an unsuitable CPU, so would be very grateful for guidance.

I have a Phenom 9950, which is socket AM2+, in an Asus board of similar age. I want to put this machine back in to use incurring as little cost as possible, but also to make it 100% fanless, and therefore need to replace the CPU due to its high TDP.

Could I put any of the currently available AMD CPU socket types in to this board, i.e. AM1, AM3+, FM2, FM2+

Cheers. It's an Asus M3A79-T Deluxe.

It would be doing office work, playing music, and in theory - occasionally - playing some old RPG/strategy games, but nothing from this decade.

It has to be a 100% silent rig though, as will be sitting about 50cm from my right ear. Therefore needs to be a low TDP that I can passively cool. Research indicates the existing Phenom 9950 has either 125W or 140W, so must go.

Thanks to everybody for their time & assistance.

I found a AD605EHDK42GI on the auction site, which is a quad-core with a stock speed of 2.3GHz, and a TDP of 45W. It'll go in with a silent copper monster known as a Nofan CR-80EH, good for cooling up to 80W or so it claims...

My advice though would be underclock/volt your 9950

I did consider doing that, but my (amateur) way of viewing it was that by reducing its performance I'd be bringing it down to about the same level as a lesser chip, but introducing a risk of me screwing it up with the settings and frying the chip.

A bit of research showed there wasn't much in it between my existing one and the one coming, in terms of benchmarks. Don't tell anybody in Members Market that though, when I rock up there one day with a 9950 to flog.

You'll still probably need a fan on the case to keep up a bit of air movement.

What an odd design for a cooler!

Found a detailed review (in foreign!)

As the review says, the important thing is:

CR-80EH로 모델명의 80은 제품이 감당할 수 있는 TDP인 80W를 의미하는 것 같습니다.

I think the idea with the design is a basic 'get that bloody heat away to anywhere but here'
