4790k Temp Issues

[BlueClown]

Hello

I bought a whole new computer this holiday (list below), and im having kind of a doubt with my cpu temp. My friend got the same cpu as I 4790k, with turbo enable he runs at 36c iddle and between 55c to 65c while playing, this with the stock cooler. Mine with a Cooler Master V8 GTS, with Turbo OFF runs at 42c idle and 66c to 75c (47c idle and 70c to 83c while playing with turbo on) while playing some of the same games with the same settings, those are not dangerous temps (yet) but still, I feel like i just bought a 90$ paper weight. We live in the same place so room temp should be about the same.  Im planning on doing some more tests (using stock cooler, asking my friend to lend me hes cpu) Just wanted an opinion in the meanwhile for why could this be. And im pretty sure I installed the Cooler correctly, so lets assume is not that (for now). Thanks.

The games we used to test are Dota2 and The Witcher 3. (all maxed out)

MotherBoard: MSI ATX DDR3 2600 LGA 1150 Motherboards Z97 GAMING 5
CPU: I7-4790k
GPU: MSI R9-390

Ram: Corsair Vengeance Pro 4x8GB DDR3 2400MHz
PowerSupply: Corsair RM Series 1000 Watt ATX/EPS 80PLUS Gold-Certified

Even-though we are assuming that it is seated correctly etc. This is still the first thing I will check, mainly because I ran out of other options. Just wiggle the heat sink and if it has a lot of play in it, it is mounted incorrectly. If it is firm, then it is fine. Also, you can look how much thermal paste is applied because too much can cause problems. (Depending how far you want to go with taking it apart)

the thing is, i already did, twice, the last time i already tighten it up so hard that my motherboard started to bend (i know this is bad, thats why i stopped there), and if thats not tight enough im better up just going straight up to the stock cooler. I will know for sure when i test the stock cooler later today or tomorrow, thats why im saying that just lets assume is installed correctly.

Ah okay. I would just wait until you get the stock. There is not much you can do software side apart from underclock. But 70c will be fine for a short while.

Does the fans even spin on ur V8? If i remember correctly the fans on the v8 can go down to very low rpms. Maybe u try to set a custom fan curve in ur bios if you really want that cooler temps. Also take a look at how much rpm the cpu cooler is running at load. (HardwareMonitor)

Heat pipes develop a 5-8c temperature gradient across themselves to work where as a solid block of aluminum does not.  So at very low TDP (idle) ?Maybe? the stock cooler wins? maybe?

 

That said I lost the lotto as well with my CPU between cores 1,2,4 and core I have a 8c difference where core 3 is always 8c colder...

Manage to lower temps, its seem that i really was thermal paste overload. Still having kind of high temps thou. Maybe my room is just too hot.
Putting the Stock Cooler did nothing, even worst. So after some testing i BELIVE, that found my problem and have no means to fix it. I knew team red was hot but not this hot, that GPU alone is responsible for elevating the temp of the whole case every time its on load (so far it maxed out at 88c), so i guess my next move will be getting an air conditioner and put it right next to my computer. Or jump back to team Green.

Another Problem im having is that i didnt do my homework before getting that PSU, and withou the Corsair Link i cant change the fans to turn on based on the temp and not the power usage so the GPU is also heating that one up. Does anyone know a workaround? (will go to google now)

Eh, what? Does it intake outside of case or inside? If it intakes fresh air from outside the case, having GPU close doesn't matter at all.

I dont know what i was thinking, totally forgot it was intake... my bad.

Still manage to get Turbo Enable with 39-40c Idle and 64 to 70 (with a 60% load) was late already so i wasnt able to test with more cpu heavy games or stress tests (will do it today). Im guessing that the last culprit would be my room temp, I live in a hot country and with no air conditioner its seems like "ok" temps (still doesnt explain how my friend has lower temps thou, maybe really its the gpu he has a gtx 970).

Thanks for all the reply anyways.

His CPU cooler is probably running at high rpms. Ur is very silent i think. U ever heared his cpu cooler?

A difference in ambient temps perhaps? and you are running an R9 390. Dissipates more heat than say a GTX 970.
