Hi I recently built my computer with an intel i5 7500 (still buthurt about coffee lake) but I have been using the stock cooler but then realised it was too loud for even when it's idle . I was looking for a compatible cooler that was under £25 but willing to speld a little more for a decent one. I did see the cm 212 ego but was too loud at 36 db. The pure rock slim from be quiet is cheaper and quiter at 25 db. Is this good and are there any other quiter ones or better value thanks in advance.
