I would like to upgrade my Athlon X2 5000+ to a Phenom II X6 1090T with my Crosshair II Formula motherboard (CPU is supported, I verified it).

I currently mount an ASUS Arctic Ice cooler which goes fine for my 85W CPU. I wonder if I have to change my cooler for supporting this new 125W 6-core CPU.

I would like a great modding cooler, possibly with a fancy look. But I don't want to buy another cooler if mine is fine for this CPU.

I own an NVidia-branded case with green-glowing fans inside (7 silent fans + CPU and PSU fans), so green would be a great colour (rather than the blue of my current cooler).

I found Cooler Master V8 cooler which seems to support additional (how many?) 12mm fans, for which I can use my fancy green fans. Do you have other ideas?

My questions are

  1. Is my current fan good for the new CPU? I don't think I'll stress the CPU too much because I abandoned SETI@Home after it burned me two PSUs (and I also have 3 video cards!!!!!!!!! 9 parallel executions :| too bad), but I'm a hard gamer
  2. What CPU cooler would you suggest me to buy?

Wow, you have an Athlon X2 500+? Didn't know such a model existed; and the jump to a 3G+ hexcore will really blow your mind (SCNR) – Jürgen A. Erhard Dec 10 '10 at 1:29
Hahahaha good one ;) I mistyped 5000 – usr-local-ΕΨΗΕΛΩΝ Dec 10 '10 at 18:57

It's probably a good idea to replace the heatsink/fan when you replace the CPU, even not considering thermal issues. After all, fans are moving parts, and wear does affect them. Plus, as @MBraedley points out, the new CPU is probably going to come with a suitable heatsink anyway.

I can only accept 1 answer, but I would have also accepted the other one for the second comment. You're right, fans should be replaced after several years to keep cooling efficient and durable. But also, I should not care about the degrees if just a few – usr-local-ΕΨΗΕΛΩΝ Dec 11 '10 at 13:58

Most new CPU's come with an appropriate heatsink and fan. I would suggest testing your current cooler against whatever comes with your new CPU. Whichever heatsink keeps your CPU colder is the one you use.

Sorry but the new CPU comes with an old-style (and noisy) fan I don't like. I threw my 5000+'s fan because when I was on the phone once with my PC turned on my fried asked me at a point "are you still drying your hair?". I would like to use a modding cooler either like mine (if it's suitable) or a new one ;) that was my question – usr-local-ΕΨΗΕΛΩΝ Dec 10 '10 at 20:16
I would still do a comparison between the two. If you're only running a few degrees hotter with your old fan, you should still be fine. – MBraedley Dec 10 '10 at 21:14
