CPU and GPU temps

[dotnerd]

I would like to see this monster.

Apologies for hijacking most of this thread.

Oh it's big now.
Added an AX1500i too just so the commander can give me some stats. (yes, overkill of note.)

I am normally not hesitant to show off but I am ashamed of the amount of RGB I have now , here goes.
Panels off in first, 3 bottom intake (+ filter), 3 out at top, push pull out on rad.








Again not saying the OP should go this route, but showing you where I ended after having the same problem

Correct me if I am wrong all, but putting the side panel back now would channel the air more ?

Rebeltech have Noctua in stock.

Replaced the Side panel and the temps went straight up. the GPU appears to dissapait heat into the case as it is not extracted by the GPU shroud.

and the fans does not move enough air in the case to exract it.

Oh, sorry about that, then just leave it off for now.

Sorry for hijacking!
This beast is amazing!!
That RGB is tasteful though.
Quick question, you haven't considered going into custom loops?

I have, but I am about to upgrade the system so sweating this a bit longer before wasting money on parts that may not be ideal for whats may be coming.

As lekker as that CPU is, it runs pretty hot and is not really paired well with that cooler. In fact, I doubt there are many fan based coolers that it will be happy with. I would (if it fits in case) try a 360 AiO and be done with it. Thats pretty much the best you can do with regards to surface area for dissipating heat. If you want to go all the way make it push-pull with by adding 3 additional fans.

Again, if it fits

He needs a delid, I run mine 5GHz on air with temps just a bit past 70 when stressing the cpu, but I had to delid the thing first, a bigger cooler is almost a waste of money if you dont delid the 8700k.

I had a look at delidding and with my skills and tools I wont attempt this at all haha. will most likely end up breaking it.

Full disclosure, I didn't read much of the previous comments so someone probably said this already so,

The CM212 is ok for non K cpu's. It is especially not good for the 8700k as the 8700k runs VERY hot.
I had this exact combo while I was waiting for my AIO CPU cooler. Bad combo

So the bad CPU cooling is pushing hot air into your case and heating up your GPU.

Temp solution: Remove side and front panel, you should get around -7c on CPU and maybe -20 on GPU.

Long term solution, replace the weak CPU cooler. Preferably AIO so you don't circulate heat back into the case

Thanks for all the input guys I really appreciate it.

I used the logger as dotnerd suggested.

I first started te replace all my Antec Prizm 120 ARGB fans with my Coolermaster Sickle flow fas as they havea higher CFM.

I ran it and my CPU avg was 60 C and peaked at 72 C
My GPU was still high with avg at 73 and peak at 80 C

I then did a few seperate test:
Only Side panel removed
Only front removed
Side and front removed

My best results were with the side and front removed.

My CPU avg was 54C and peaked at 61 C
My GPU was better with avg at 69 C and peak at 71 C

I have custom curves setup for the CPU fans and the case fans as well.
The fans for the CPU and the extracting fan at the back can be setup a bit more aggressive.

I understand what all of you are saying about the CPU cooler and I will definitely get another/better one as the consensus is that this cooler wont suffice. The one Evetech gave me was a small 80mm single fan Antec C40 cooler with the upgrade kit so I just used my old one the Cm 212 as I thought it would be better.

I had a feel and the cooler extracts the CPU heat very well, so I dont think it is Thermal "leakage" from the CPU causing the GPU to heat up.
I just think the intake case fans in front is not pushing enough air over the GPU to move the hot air out of the case.

I think I'll reinstall the components in my old case. CM690 V1 (bought it in like 2009 I think), that case have a side intake directly over the GPU which I think will work better.

I just spend quite allot of money on the new case and fans so I cant afford another case with better airflow at the moment. The Cooler would also need to wait as I dont have the funds at the moment.

What AIO will you guys reccomend, also a new case as I dont think using the AIO at the intake would work as it would completely block the intake.

With a bit of adjustment on the GPU fan curve as well as the CPU and Case Fan Curves i got it a bit better.

CPU now at 49 - 54 C
GPU constant at 67 max 71C

This seems a bit better.

HI all.

I had a look at a few radiators, which one would you suggest to use with the i7-8700k?
Coolermaster ML240
Corsair H100i RGB Platinum


or should I rather have a look at a 360mm radiator?

Im not just sure how I would place it in the case as the intake is where the 360mm rad would be needed and would thus choke the system.

The top (Exhaust) can take the 240mm rad, so thought I would rather use the top 240mm slot for the CPU Cooler?

Thanks in advance all.

I'd go with the Corsair and use it as top exhaust and get proper front intake fans

I also leaned more towards the Corsair AIO.
Which fans would you suggest as intake fans, would like for it to be RGB as well.

What case fans do you currently have in front?

 

[Ultra]

What case fans do you currently have in front?

I currently have 2x Coolermaster Sickleflow and 1x Coolermaster Jetflo as intake fans.
Used to have the Antec Prizm fans as intake fans but the coolermaster ones are about 20-30CFM more than the Antec Prizm.

 

[dash09]

Regarding the gpu, I have the same 1 and in my corsair 280x the temps are not good at all. I found undervolting to be a good solution, for now, since I'm not out to push the gpu to max performance the undervolt works pretty well at keeping the gpu in the mid 70s under load, with a performance loss that is unnoticeable with the types of games I play. Without the undervolt my temps were similar to yours.
For reference my gpu runs at 0.950v at 1898mhz (I dont know if this is good or bad as it is my first time undervolting)

As for the cpu, my 7700k even cooled by an aio touched 80 degrees often, a delid dropped that by a good 10-15 in most games. Another possible temp solution for you until you find a better cooler is to just disable the intel turbo, that should knock off a few degrees, not much but its worth trying.

The fans in my case all run at pretty low rpm now, if I ramp them up I could get better temps but for now the pc is very silent

Personally I would change those two Sickleflow fans to the Jetflo - seems to have decent CFM. Otherwise, if it has to be RGB, maybe go Noctua (yes, im a fanboy) and get Phanteks Halo frames (available at Wootware)

 

[heinreich]

@G3t Wr3k3d - Do a delid for this guy?

@G3t Wr3k3d - Do a delid for this guy?

He can gladly hit me up if he wants to look at doing a delid.

I had my 8700k running at 5.2ghz daily with temps lower than his current temps. A delid would certainly help with temps but a better cooler would be recommended aswell

Thank you for all the information.
I ramped up my GPU fan curve and its much beter, the default silent fan setting just boils the card and when the fans start up it just takes forever to drop the temps. so i have a slow fan curve at low load and as soon as the temps get high I just made them more aggressive.

I'll keep the undervolting as an option if I dont get this sorted.

I'll have a look at a delid, i see you have an H100i Pro Cooler, is the temps still high with the cooler?

Yeah I will have a look at the Jetflo, the Sickleflow is about 70CFM so for now they are ok. will have a look and perhaps get the Jetflo and those Halo Frames you suggested. The Noctua are just to expensive...

Cpu temps are better than what they used to be, but not the coolest I've seen. My bro has a non k 6700 and using my old v2 h100i, he never touches 60 degrees, and he has the same case. Some cpus just run hotter than others. My temps aren't in the region I would consider dangerous.
Your resolution and framerate will also affect your gpu temps, bear that in mind. The undervolt knocked off about 7 degrees for me, and again the performance loss is unnoticeable to me.

If you're going to change your fans just go big, noctuas or ek vardars (these push some serious air), dont waste your time on rgb, all these fancy looking fans have crap cfm and static pressure, they just for looks. I've got noctua chromax 140s as intake and 120s on the rad as exhaust. 120 vardars directly below the gpu

Noctua redux fans, I just sold all mine but if you can find some then buy them. The build quality is lower but performance is on par with more costly noctuas

Those temps are nothing...

Got a 8700k, all cores @ 4,7ghz with a Coolermaster ML240 AIO. GPU is a Palit RTX 2080 Ti

The coolermaster case has three 120mm intakes in front, and one 120mm exhaust at the back. The AIO is at the top and extracts heat with 2 x120mm fans (push)

So thats 6 x120mm fans.

My CPU idles at roughly 45C or so on a warm day. When i play games at get back to windows, i see temps in the high 90's before quickly coming down again. PC has been running perfectly stable for more than a year

Those are high yeah, my CPU temps are higher what I would like them to be. It idle at 35C in windows.

My main culprit is my GPU releasing an insane amount of hot air into my case and the case not being able to extract it. i've played with my fan curves and it is much better, even have a mystifying Standing Fan in the room to cool it a bit down.

I only wish you could get more cases with side intake fans across the GPU.

Yeah same here, the GPU makes an insane amount of heat, the room is way hotter than other rooms

 

[Ultra]

I've had a thought to mod the case, the front intake is very small for the fans so i want to cut it open and replace it with fan Filters/mesh to allow better airflow.

I've never done something like this before so if someone could perhaps assist with places that sell mesh/filters i can use it would be awesome.
This is the Front panel im going to attempt to mod, my plan is to remove the dark solid area and replace it with the same type of mesh as the small vent on the side.

Easy

Get n drill, put a 100mm circular drill bit on (R50 at builders), find a 120mm grill fan (R10 at an electronics store), measure twice, cuts once

Eish sounds like that 8700k needs a sexy delid. Mine idles at 24 or so. Maxes out in gaming at 59c +- a degree. 74c under small fft load in prime95 5ghz 1.36v all core full avx, on a corsair h115i pro, Ml140s fans running at 1000rpm.

Just looked up your case now, that needs to go. Change your case
