I'm looking to overclock my CPU and they first thing i know is that you want to change your cpu heatsink and fan depending one what your using. I'm using the default right out of the box fan. The thing is loud and doesn't do a good job Intel fan that is comes with. There are 3 different cooling replacements i am looking at for this over clocking and I am going to want to try and get this to atleast 4.0 ghz and the cpu is the sandy bridge 2500k 1155.
And last but not least the case that i will not be changing as of yet for this upgrade is the rosewill challenger. Also on a side note i have 4 sticks of the low profile ram if anyone was wondering if ram height would be an issue.
+1 on the hyper212.
It will be quieter and do the job.
A 4.0 oc is not that aggressive.
Liquid cooling tends to be noisier, more expensive, less reliable, and will not cool any better in a well ventilated case.
And... there are too many tales of woe where a liquid cooler leaked and destroyed everything.
