Our processor coolers (left cooler) vs. stock cooler (right cooler)
For years processor manufacturers, both AMD & Intel, have included a "stock" cpu fan/heatsink cooler in the box. It's no secret that the cpu stock coolers for pre-built computers and even custom computers are underwhelming to say the least. Stock cpu heatsinks typically cause your processor to run 20-25 degrees C. hotter than your average aftermakert cpu heatsink. Plus, stock cpu fans produce so much more noise than aftermarket fans.
In addition, stock cpu coolers cause your processor to "thermal throttle". In other words, slow down due to heat. Most processors' max temperature is 100 degrees C. Let's say you have 3500 mhz. (think "miles per hour," so 3500 mph) processor. If the temperature of your processor reaches around 80 degrees C. or more, it will actually lower the speed to around 3100 mhz. (3100 mph) or even lower to keep the processor from heating up further.
We recommend using a cpu heatsink with two copper heatpipes or more. The PC Smith1 offers to upgrade your cooler, replace the thermal paste on your processor, and tune your cpu fan all for just $50 + the cost of the cooler!
