After Market cooler for non-overclocking CPU?

Hello all!

I was wondering, is it worth getting an after market cooler for my i5-6600? When I play games like Over Watch for an hour or more, it can reach temps up too 73c to 75c.

Thanks for the help!

Eventually the paste may dry enough on the stock one (4-5 years minimum) and it might be worth it then. I've only ever had to replace one stock cooler and it was on a 8 year old Intel rig that ran every day 24/7 for all 8 years. And it would still keep it okay until at 100% load. I've got many 7+ year old builds in the wild that are still on the stock cooler.

Wow, that is impressive. Thanks for the help, I will save the money and do something else with it.

Cheers :)

I wouldn't worry about aftermarket HSF for non-overclocking unless you require something quieter, a custom form factor or possibly for cosmetic reasons.

Reliability-wise, material and manufacturing defects aside, semiconductors without consumable internal structures (EEPROM and NAND for example) will typically last 20+ years when operated within specs. My audio amplifier is over 30 years old, still works fine apart from switches that could use a cleaning and putting in some new input filter caps wouldn't hurt either.

The stock paste is already practically dry, which is perfectly fine since it is the solid particles that provide practically all of the heat transfer. The silicone oil is only there to keep the particles from turning into airborne dust and allow the paste flow under pressure and heat. The only time you should run into issues from paste "drying" is when you accidentally nudge the heatsink and break the paste layer that got tightly packed over thousands of thermal cycles since the original application.

My i5-3470 with stock HSF is still good as new four and a half years later. On my Core2 though, I nudged the HSF while cleaning the interior around the third year mark and temperatures shot up to 90C. Nothing I did to the stock HSF helped and I ended up getting a 212+.
