Hey LTT Community,
So for about a year, I had an i5 4670k overclocked at 4.0GHz being cooled by a CM Hyper 212 Evo, idle temps were about 28-29C, under load they never went over 50C even while rendering a video and using prime 95 to stress test. About 3 months ago, I upgraded to an i7 4790k and expected temps to be higher since it's more powerful than an i5 obviously. Temps were about 8 degrees hotter with the i7, no big deal. Well last week, I wanted to switch to watercooling and decided to buy the Thermaltake Water 3.0 Ultimate all in one watercooler, which is a triple 360MM radiator that came with 3 static pressure fans by thermaltake. First time I installed it, I didn't seat the CPU block correctly and tried it again and got it the 2nd time. I immediately wanted to compare the temps from air cooling to my new watercooler and was very confused by the results. At idle, the temps are definitely lower with the watercooler sitting at about 24-25C, but under load is what confused me. Like I said before, air cooling under load on my i5 never went above 50C, but after upgrading to my i7, temps under load were about 64C which is fine for me. I did a stress test in prime 95 and temps on my watercooler (i also have 5 other 140mm case fans) were in the 70's, with the highest temp getting up to 87C. I'm rendering a video currently with the average CPU temps being about 84C... I don't understand. I'm a noob with watercooling 100%, but isn't it suppose to make your temps better than air cooling? I THINK I remember hearing that watercooling temps depend ALOT on the room temperature and temperature outside too and my room is always fairly hot, would this be the cause of it? My watercooler was $130 and my aircooler wasn't even $30 and it seems to perform better by quite abit. Anyone mind explaining this to me? I'd really appreciate it.
