Is it a good idea to swap a case fan for a 120mm AiO cooler?

I'm considering upgrading my CPU cooler for my 7600 and I'm thinking about replacing one of my case fans with a 120mm AiO cooler. Right now, I have a micro tower case that has five fans total โ€“ two exhaust fans at the back, one at the top over the CPU, and three intake fans in the front. Would using an AiO in place of a case fan be a bad idea?

It really depends on the tower cooler you already have. Some tower coolers, like the Endorfy Spartan 5 Max, can actually outperform a 120mm AiO. If your current cooler is managing decent temps, you might want to stick with it instead of switching to an AiO, which doesnโ€™t typically provide the best value for cooling performance.

120mm AIOs often don't deliver compared to decent air coolers. I've got a 7700k and swapping to a 120mm AIO didn't help much with temps at all. In fact, I had to configure mine in a push/pull setup just to keep it manageable. A solid air cooler usually keeps things cooler, especially for modern CPUs with higher thread counts. You might want to reconsider if you think the AiO will cool better.

ChillTechMaster: Thanks for sharing your experience! I definitely didn't realize they were that ineffective at cooling. Might just stick with air cooling after all.
