Cooler Master Hyper TX3 CPU Cooler. HYPER TX3 ALUMINUM FIN FOR AMD INTEL LGA 775/1156 MB-CP. 92mm - 2800rpm 1 x Sleeve Bearing

Been running this on my i5-2500k for almost a year now, and in that time i've come to recognise just how great it is. Temps with the stock intel heatsink were hitting 70 degrees at 4.2ghz. Now i run daily at 4.5ghz and even during the most demanding applications and games don't see over 55 degrees.
Incredible cooler for the money. I used Arctic Silver 5, and the combination of a cold day with this heatsink let me do Intel Burn Test at 5.1ghz without the CPU throttling itself.

Could not recommend this cooler more.

CM TX3 comes with the single install 92mm fan of course and includes hardware to mount a second 92mm fan, I suggest you do so and grab some aftermarket thermal paste.
Extra fan same make and model as the OEM that comes with the TX3 is $8-9 and AS5 thermal paste was $9.
After that there will be no need to worry about your cooling solution anymore.
So for the $23 for the TX3 and the add-ons it comes to around $40 or so.
You have a smaller size workhorse that can fit almost in any set-up, comes close but does not interfere with any RAM slots or cooling mosfets and push/pin for the easiest of installs.
Currently cooling the following:
3570K @ 4.2GHz
2500K @ 4.5GHz
2500K @ 4.0GHz
