im building an i5 3570k rig and i still have to order a cpu cooler.
but there are lots of options and i feel a little lost.
my budget would be about £25 and i wont be doing any overclocking right now, however later down the line i most probably will overclock it to 4ghz so please keep that in mind.
i live in the uk so please no newegg links
amazon.co.uk should do the job.
