What is the actual difference in performance between 240mmvs280mm aio rads? I'll probably have my delidded 7700k overclocked to 1.3-1.35v. I have a kraken x52(240mm) and a krakenx62(280mm), the x52 fits my current setup better but I'd be willing to move a few things around and buy bigger fans if needed for the x62. What kind of differences would I see if I were to test them both? I would test myself but the CPU hasn't arrived yet and I need to return one soon. Thanks for any info!
