Hi everyone, sorry for my english. I'm undecided on what product buy. I've tested the NH-U14S and NH-D15 making a comparison. The temperatures are the same in every game i tried (45-50 C°) and in idle both hit 30-35 C°, so why buy one then other if NH-U14S give more compatibility and more space? And why the NH-D15 with 2 tower heatsink cool the same as the NH-U14S? I've tried with intelburntest, i have an i5-4670k clocked at 4,2 ghz and 1.240 V. Both hit 68-73 C°.Thank you for your answers.
