First build. High temps. Help! i5 8600K

[JKR]

I just built my first rig. I have an Intel i5 8600K in an ASUS Z370-F Gaming mobo. The mobo came with a cpu “installer” to help place the cpu correctly into the slot without damage. However it doesn’t say to remove it and seems to imply to keep it in place situated around the cpu. Then with the entire unit in place, then you lock down the socket arm into place leaving the plastic housing still there surrounding the cpu. Seems that plastic would help retain heat! Plus, after purchasing chip and using it for a month I found out that the Intel chips ARE running hot. I stayed away from the Ryzen chips for this reason. Ugh! My basic info is: 1) My cpu temps seem pretty high for a new chip; 40c or so without load. 2) I am using a Corsair h105 240 AIO to cool it with MX4 Carbon as TIM. 3) Already replaced stock Corsair fans on the rad with Noctua Industrial 120 PWMs (3000rpm and decent static pressure). I have an additional Noctua 120mm Industrial fan as exhaust through back of case. 4) Placed AIO on top of case pulling air into case. 2 stock Corsair 140mm on front pulling air into case. EVGA GTX 1080 SC ACX 3.0 with 2 fans on bottom of GPU but pushing hot air back into case. Placed PSU on bottom upside down, pulling air from inside case towards outside back just to get air moving. There was a dead space under my GPU. Hot air just stayed right there. Case is a Corsair 450D with Aeroslots on back so no solid pci slot covers. Entire back of case is pretty open/ mesh-like. Using Demciflex filters on all intakes. Removed all cages from inside case except the one housing my hdd on the top which is bolted on. So inside case has a lot of room.  Exhaust fan has no filter.  Questions: 1) Should I take out the plastic installer from the cpu socket and if so will the cpu fit the ASUS Z370-F 1151 properly? Will it fit snug enough to get proper connections? 2) Should I keep the plastic unit in place and just repaste with a different TIM and reseat the heat sink? 3) Should I be exhausting the air through the AIO from the inside to the outside? (Seems counterintuitive to me though since it would be pushing hot air from the case through the radiator which is supposed to be cooling the chip) 4) Delid the chip and replace Intel TIM with Conductonaut? 5) Do AIO speeds matter? What should the pump percentage be and what about the actual AIO fan speeds? What is the ideal speed setup for maximum rad cooling with an h205? 6) Are my fans in the wrong places/orientations?? Could they be competing with each other’s airflow? Causing conflicting air patterns??

So many questions!

Sorry! But it’s my first build and although everything does work. Temps are a real problem!

Help!!

I have No experience with the 8th gen Intel lineup or the AIO you are using, so I'll have to guestimate.

40 sounds a bit high for idle with that AIO.

 

First off, I'd say your build is best off running air from case out of the AIO. But be sure to have an intake fan to feed the build with air.

 

Second, you might be running PVM on the pump and fans. Most MBs have 'silent' features built into bios, limiting power to CPU fan when it's cool, would explain what you are experiencing.

Try locating fan speed control, either in bios or through OEM software (Asus ai suite).

Then tweak to fit your cooling vs noise preference

I'm more interested in your load temps.

It could be limited because TIM inside your CPU … that's usually problem with Intel CPUs.

I don’t think that’s how hot the 8600k should be running but I don’t have any solutions UwU

I assume you mean the plastic cover of the socket? I havent seen one before. remove it. No plastic should be near your CPU after installing it, there just isnt need for any.

no need for that when you have exhuast fans like these 2k RPKM noctuas. Make sure you crank up all of them's speed though.

not in a rush for that

for testing purposes, turn them all the way to 90%. I'd keep the pump and fan speed at 30% minimum for an AIO during long term use.

By load temps we mean hammering it with a stress test. I myself use Prime95 small FFT, but IBT (intelburntest) works as well.

Something everyone always seems to overlook; what are the temps like in your room?

Ambient temperatures matter. If it's a warmer room, your temps will be higher. Honestly 40 doesn't really seem that high to me if the room is warm.

Are those the CPU load temps?

[Mamonos]

According to my experience, 40C at idle is a pretty normal temperature for 8th gen CPU.

That said, idle temperature does not matter that much.

@Jurrunio

The plastic installer is not the conventional plastic socket cover that originally comes with the board and then pops off when the lid is secured. It’s actually a frame like device to click the cpu into place; then the entire thing fits into the socket. Never saw one before but had heard of them. 

 

Keep the AIO pulling air from the top outside air into the case?? I’ve got them running at 90% at 50*C

 

I actually have run 3D Mark, Fuzzy Donut, Cinebench and hightemps get to roughly 67*C ish at highest. Just at lower loads it seem to run highish

@Mamonos

So the high cpu temps are ok for that chip then?? I dont need delid and replace ihs TIM ??Also meant @AskTJ Those are mostly idle temps with fan curves running at approx 70% at 40*C

@dizmo

Room temps are approx 24*C and ambient temp inside generally 1-1.5* higher in case

@Simon771

Was wondering if you delidded and replaced Intel tim??

Like the one for Threadripper? I'd remove it once you get the CPU inside the socket. Not like there's benefits by leaving it on after installing the CPU.

it's fine.

 

50C is super good, even 67C. My top temp for extended periods of use is 80C. Besides, auto voltage always goes too high, which means you can get more frequency with the same voltage (enter it manually or use offset mode, just not plain auto) and temps.

OMG. I am so confused!!
