New CPU Cooler

[MH_Wadester]

Hey lately i have currently been looking for a new cpu cooler considering that i still have the default stock cooler that came with the cpu and/or case...

Which isn't really doing its job too well not cooling and extremely loud (doesn't help that the computer is in the hottest room thats like a oven through out the day). I would like to aim for something between $30-60$ excluding postage costs (preferably something cheaper thats half decent).

I was wondering if you could recommend a good cpu cooler for me? I'll list all the main pieces of hardware in my case so you can have more information in as what i would be able to use.
what i have:
Motherboard: Gigabyte GA-MA790XT-UD4P
PSU: 620W HX Corsair
Graphics Card: ATI Radeon HD4870 x1
CPU: AMD Phenom II x 4 955
Fans: 1 120mm bottom fan, 2x 120mm top exhaust, 1x120 rear exhaust
Case: CM 690

Thats the main components of my computer and also i live in Australia so i dont know if all the products that might be good for me will be available.

PS: To save you having to read about it the motherboard is AM3 socket.

well thanks for help in advance.

If the fan is making noise, it my not be moving the air it needs to.

For best air cooling, I would start with a silver-based heat-sink compound, a copper heat-sink, and a ball-bearing fan. It is hard to recommend any details beyond that. If it were me, I would just clean off the old compound and replace it (with silver-based), and if the fan can be replaced separately from the heat-sink, do that. You may also be able to tweak the fan speeds in the BIOS (and maybe under-clock).

With a hot room, you may be forced to "break the bank," and look at a liquid-cooling system.

These are just examples... make sure they will work with your system & case!

Good Luck

It may also be worth thinking about a better air flow all round. you could try leaving the side off the machine and have a table fan running. Make sure (and I'm sure you have) that there is no dust clogging any of the vents or on the motherboard or heat sinks.
