Alpenfohn K2 @ £60 does a very good job.

To get 4.5 a solid air cooler is needed your looking at a Prolimatech Mega Harlems or the like. If you want 4.8 then you need the Alpenfohn or a Noctua D14 or if you go water an Antec h20 920, all of these will keep your temps in the low 70's @ 4.8 when stress testing and high 50's low 60's when doing normal stuff.

Come to think of it if you can find one the Thermalright Silver Arrow is very well priced for the performance it gives, equal to the D14 and beats the Antec 920.

You can't go back and do it again, but you can go forward and do it different.

In all honesty the chances of your CPU being able to hit 4.8 on a very expensive air cooler but not on a middle of the road one are small. However you might as well go the extra 20 quid or so.

If you wanted though you could go for a 25 quid cooler and you'd probably get most of the overclock you would get with a 70 quid cooler. Sandy Bridge produces a lot less heat than previous generations that stretched the capacity of air coolers.

Gelid Tranquillo keeps mine around 60-65c @ 4.5ghz at full load. A snip at £25.99 as well.

ok. thanks for the useful replies so far.

I really think I'm going to push the quiet thing. I think I'm going to exclusively use spectre pro fans in the case, so if i decided to use 1 (or 2) of these instead of the stock fans (or even better a heat sink that doesn't come with one) would this change anyone's opinion? and i think i would rather be quiet at 4.2GHz that louder at 4.5....

Asus Arctic Square is better if you can find one though.

If you take it easy, around 4ghz. Though I would suspect the temps to be borderline.

As mentioned sandy is a relatively cool running set of chips. You should easily be able to get away with clocks as high as 4.5ghz on a decent £30 cooler. Any higher and you should really be looking at high end air or water

iirc I had my 2600K @ 4.6ghz with an arctic cooling freezer pro 13 hitting temps in the low to mid 70's. H80 @ 4.8ghz in the high 60's low 70's and now custom water @ 4.8ghz giving temps in the high 40's to low 50's.

Remember stress temps, especially in IBT will be a great deal higher than heavy gaming stress. When I had my H80 gaming temps would often be 15c or so lower than IBT temps.

I have a 2500K with a Xigmatek Gaia fitted and it does 4.2 ridiculously easy (nice and quiet too), that's in an Antec 300 with only an extractor fan so not the best ventilation.

I reckon it could do 4.4-4.5ghz easy enough with one as long as you don't have a stinker of a chip and need to start throwing high volts at it, once you start pumping the volts you're going to need one of the more expensive coolers, if you have memory that runs at 1.5V or less that should also help with temps.

I have a Corsair A50 on my 2500k £21 inc VAT

also, I have used a THIN line of MX3 compound

Running 4.6ghz 24/7. Fully stable (loads of IBT / Prime95 suicide runs)

Temps have never gone over 57c

This is using one corsair fan which came in the box. I use Akasa Blacks in Push/Pull but unfortunately made ZERO difference. Temps still peaked at 57c

Great result for £21. Now I may have a great chip, not sure

Is the original Akasa Venom still considered a decent cooler for the 2500k? I'm currently using one on my existing rig but want to swap it over when I do a system wide upgrade in a couple of months; or am I going to have to bite the bullet and get a beefier one?

After much research I've decided that all the half decent coolers use the backplate mounting method so I can't be lazy and I'll have to remove everything from my case to affix it

A50 looks like the best value one.

The Alpenföhn K2 looks like a great piece of kit but i cant help but think it cant be doing the motherboard any good having all that weight hanging down on it

The cheapest cooler that I have personally used to hit 4.7GHz on a 2600K is the Akasa Venom Voodoo. It was hitting around 85°C with my hot CPU though.

If you have your own fans to use the Megahalems is an excellent choice provided the fans are fairly decent. If you don't have your own fans to use with it, it becomes a more expensive option.

My Hyper 212+ performed excellently at 4.5GHz with room to spare, so if you're feeling risky that may be worth a try.
