I've actually got an H100i in my workstation at work... no leaks (thank God) but I have to laugh when I compare it to my custom loop rig at home - granted they are not remotely comparable systems (well they're both running 3570K's but that's about all they have in common).
In comparison to some of the better air coolers I've used... the performance is mediocre at best. If I compare the performance to my custom loop at home... it's absolute crap. On the other hand, if someone told me I had to get them the best stable OC possible out of any recent chip and I couldn't spend more than $100 on a cooler... I'd go CLC every time.
On my custom loop I think I spent about 7 times that much
... so yeah, it can cool everything incredibly well... but then again in the workstation that my H100i cools... I only have about $750 in total hardware including the CLC. Somehow it doesn't seem right to spend more than 10-15% of the cost of the hardware itself for a CPU cooler - on the other hand, it also doesn't seem right to cool a $2-3K system with a $50 cooler.
Naturally IMO only...
And it also completely depends on allowable down-time. I wouldn't ever build a server with watercooling, CLC or custom for that matter - but on a machine that gets regular backups... sure why not?Edited by DiGiCiDAL - 3/30/13 at 6:36am
