The last bit I need for my silent PC is a CPU cooler.

I'm not goin water cooling as I have only 1 fan outlet on my case so what is the best quiet CPU cooler;

So far I've seen the Thermaltake Big Typhoon which looks a tad too big, the Coolermaster Hyper48 which is SUPER heavy, the Arctic Cooling Freezer 64 Pro where they are worried the rubber fan mounts will go hard and break and the Thermaltake 9500 which is £40! (you can get a watercooler for that).

At the mo out of those 3 I'm looking at the Arctic (cos its the cheapest!), any others that people have seen that are quieter and better?

you might want to look at the Zalman CNPS7700-CU, its quite big because it has a 120mm fan but they do the CNPS7000B-CU which has a 92mm fan

OK heres a question for you all:

Ive been looking at the Asetek VapoChill Micro, and the price difference between the High End and Ultra Low Noise is over £10, is it just because the Low end comes with a quieter fan and fan controller, or is there any significant difference in the actual heatpipe coolers?

If not I could just get the cheapest noisyest one and fit the AcoustiFan DustPROOF Fan 92mm that I already have to the High End cooler and it would be as quiet if not quieter than the Ultra Low Noise one.

Gigabyte 3D Rocket Pro

Fan controller, quiet and got 4 blue led's!

Best coolers are Thermalright SI-120 & XP120, both of which take a 120mm fan. Get a low noise fan and you'll have quiet.

Similarly, the XP-90C & XP-90 are both good and take a 92mm fan.

The Zalman CNPS7700 is also very good and very quiet and comes with integral 120mm fan.

Also worth considering is the Gigabyte G-Power Pro, again with integral fan and speed control.

You asked for the best cooler that was quiet, in my opinion the Thermalright are best and are probably equalled by the Zalman, it's the choice of fan with a Thermalright cooler that will make the difference.

I'm afraid you only get what you pay for, none of the above coolers are less than £30.00, but they're all good.

VR: I was going to recommend the Gigabyte 3D Pro, but I don't think it's made anymore, the G-Power Pro seems to have replaced it, though I'm not entirely sure.

Yeah they is getting rare, but i've seen them around. I think your right the G Power is the new thing now.
I found some in Froogle

Thanks but the none of the Gigabyte coolers go below 20db even my old Arctic Cooler is quieter than that, plus I HATE Led coolers, so last year

Ive never seen a Gigabyte cooler go below 20db, I want something as close to 10db, I know I can get 1200cfm 120 or 92mm fans that are lower than 10db, its just finding a cooler simular to that.

I'm not into overclocking my PC as its pretty much running 24-7 so stabilty and silence is more important than super overclock speed. Most of the software I use relys more on RAM or GPU than CPU anyway, I just want this PC silent so I can have it run in the living room and not bother me.

i'd like to see one of those
