I'm looking to upgrade the from the stock Intel POS cooler in my media center (seeing temps under load up to 85c on my i5 4570S) and unfortunately, closed-loop water cooling isn't an option. The case is a Fractal Node 605, so I'm pretty limited on height. Can't really go much over the height of the Intel cooler which is around 50mm (*MIGHT* be able to get away with 100mm max, but I'd have to re-route some cables). I've read mixed reviews on the Noctura NH-L9i, but it's been probably 5 or 6 years since I've even looked at an air cooled heatsink/fan. Anybody have any good suggestions?
