Best CPU Coolers for I7 6700k Buying Guide

Best CPU Coolers for I7 6700k Guide

Now that we’ve gone through some of the best coolers for i7 6799k, it’s time to make the knowledge count. One of the main questions we are asked is what specs should I look for when purchasing a CPU cooler?

Checking Your Specs

The first thing you need to do is check the specs of your PC and figure out why you need a quality cooler. Are you looking to overclock your computer so you can push the performance to the highest possible levels? If so, buying a high-end CPU cooler is an absolute must.

If you are working with a budget and are simply looking to build a mid-level gaming computer, an entry-level cooler will suffice. Therefore, you must know exactly what you are trying to achieve with a new CPU cooler.

Air Cooling or AIO Coolers?

Best CPU Coolers for I7 6700k Cooling

You need to decide whether you want a standard Air Cooling system or AIO coolers. The best AIO liquid coolers can achieve better and more controlled temperatures than a high-end air-cooler.

To put this into context, air-coolers, on average, are better value-for-money than AIO coolers and require little maintenance. AIO coolers are a better option for serious gamers and PC users who want to achieve the coolest temperature. But that means they are more expensive than air-coolers.

Don’t Underestimate TDP Rating

Best CPU Coolers for I7 6700k TDP

Thermal Design Power (TDP) is one of the most important things you need to consider when purchasing a CPU cooler. Basically, TDP is a thermal design point that is the maximum amount of heat that is generated by the CPU that your cooling system needs to dissipate.

Make sure that the CPU cooler you buy has a higher TDP rating than your processor, or it won’t work at optimal levels.

CPU Cooler Compatibility

Always make sure you check the sizes of your desired CPU cooler in conjunction with your PC dimensions. Check the height, bulkiness, and radiator size of your cooler before you make a purchase. You do not want to force a square peg into a round hole.
