I have a 1950x with an Enermax LiqTech TR4 240 cooler for it. I have push pull fans setup on it.

I am getting what seems like very high temps with a slight overclock 3.9ghz and moderate volts 1.33
Rendering 4k footage using 80% cpu load on all cores

Mobo is Asrock Taichi and I used the grizzly compound for the TIM.

How would you know if the cpu watercooler is not working properly?
Could I have the load line set too high?

I havent changed many settings in the bios

The rad feels cool, but there is a ton of heat coming off the pc so its being cooled somwhat

I am wondering if I need to replace the 240 with the larger 360 or if its blocked or something

Thanks for the help
 
That does sound a tad warm considering the workload. My 1920X runs at 76 Tdie / 103 Tctl when hammered with prime95. (consuming 230W if you believe HWinfo) Encoding videos which is around 80-85% load it's only just edging 65 Tdie. This is running 3.975GHz at 1.325V and cooled using the ropey original EK TR4 block and 480+240 radiators.
 
That is a lot of radiator space Kei. I would check on the thermal paste application, and also fan settings on the radiator.

If you're putting that much load on the CPU, it will be drawing a lot of current/power so I suspect the VRMs will be generating a lot of heat too - with a liquid cooler on the CPU, do you have enough case air flow to keep these cool? Heat will soak into nearby components via the motherboard if the VRMs are very hot.
 
I had the case open yesterday to get more airflow and it didnt make any difference at all.
Normally there is 3 intakes at the front - 2 blow over the rad with 2 pulling on the rad and the bottom intake is for cool air to the gpu

The GPU is a GTX1060 and just idles making videos.
There are 2 exhuast fans 1 on the rear and one on the top

The case is a Corsair glass one with the 3 front RGB LED's a good case.

It was a big render using Denoise and lots of Luts etc - a 7 hour render but the temps were causing the CPU to throttle.
It throttles at 87c - you watch it doing it live.

I hope the 87c is the 27c offset people talk about to give the safe 60c Temp overall thats suggested.

Its the spikes - it spike 10c quite often so I have lowered everything today - down in the 1.2v region still at 3.9 - will see how I get on.

It is hot atm - much higher ambient temps - but something seemed up.

I think I need more cooling - PIA to do it

That is very high indeed. I have the same CPU with a corsair H100i V2 running the same board atm and idle temps are low 30's and load temps @4ghz are around 65c. I'm also running 4 gpu's alongside it and don't believe that I have seen temps anywhere near that high.

I just checked in on my kit from work and my CPU is under 80% load atm running 59.5 degrees. If I pummel the thing 100% load it can push up towards 70 (cooler running in balanced mode) but never really goes over. CPU voltage hovers around 1.4v @ 4ghz.

I am also running the same case i think. Corsair 460 x and the main GPU is Vega but I also have 2x rx570's and a rx560 in this case.

Yeah that's the same case, I thought something seemed off as the whole rad surely should be getting warm not just the pipe from the block - or is that a wrong assumption.

Wiht the Vcore 1.28 today its settling in the 70's going to 80's. Ambient room temp is probably 25c or higher.

Sound like could be a cooler fault as I suspected?
 
The whole top of my case is getting warm - could it be my bios settings.

How have you got things setup in bios ??

Thanks for the help btw
 
No, you don't want lots of TIM - just a thin layer to help interface the two metal surfaces. It's basically designed to fill small gaps but not stop the surfaces touching directly.

There are several Thermal Grizzly TIM products but they're all very good for normal (not sub-zero) use.

If the block is getting warm and some of the tubes but not the radiator, is the pump definitely running?
 
with the 10950 you have to apply a lot over a big area because its so massive.

I didnt just apply a huge dolop in the middle I placed it out over the whole cpu - I meant I didnt use the normal technique of a small amount in the middle
 
Ok, I understand now. And have you confirmed if the pump is running? I don't know what connections that cooler has, or if it's a PWM driven pump. Could it be that it's running too slow/the PWM is too low to start it?

Not going to lie I am using some cheap akassa compound I had laying around as I forgot to buy more when I swapped out the motherboard. I have a few different x399 boards as some just don't cut it for certain projects but I haven't noticed temp differences between boards.

I have the 3 intake fans at the front the same as you and have the 240 mounted at the top of the case pushing air out, I don't have a rear exhaust fan or anything like that so you effectively have more cooling in the case than I do at this point. I also have all 4 GPU's working at full chat 24/7 and 16 threads of the 32 available on 1950x fully utilised at all times. So I am producing plenty of residual heat for the case to deal with. My rad does get quite hot at times and you can certainly feel it is doing it's job. Could your cooler have a small air lock or something?

In terms of my bios the only thing I am doing is running my 8x8gb 3466mhz G.Skill ram at 3200 so im pushing a bit more voltage through both the memory and CPU SOC but I gather that this is pretty much necessary to get that kind of memory speed with all banks populated.
 
Tctl is the temperature with an offset. There are videos online regarding thermal paste application. I’m pretty sure that hardocp did one and gamers nexus definitely did. I reapplied mine after reaching nearly 90 and I got a fair improvement.
 
I can only really touch feel the rad the main case side because of the push pull fans

I have the rad vertical mounted on the back of the top 2 of 3 front fans so the front fans flow cool air from outside the case onto the rad.
Then the included fans are acting as pull

The top of the top fans blows out warm heat lower down i.e the second fan is blowing much cooler air into the case.
Like either all the heat is stuck at the top or gone by the time it gets to the lower part of the rad.

That to me seems wrong as surely the whole rad should be roughly equal temp.

The pipe from the cu block to the rad is very warm the pipe to the cpu is very cool

Is that normal??

Thanks

I just slapped cheap compound on using a sort of 0.5mm layer using a credit card. Didn't really take all that much care if i'm honest - Just slapped it on. I have changed between several boards and the difference between taking care and slapping it on seems to be next to nothing perhaps a degree or two here and there but nothing that I can say made a particular difference.
 
I dont think its the TIM application because I was careful and applied a good amount across the different areas of the cpu.

I havent built a pc in a good few years but normally thats never an issue.

I just turned the pc off after a 2 hour render with temps 80c in Ryzen Master.

the rad fins feel cold but the inlet pipe is very hot - surely they should be same temps roughly?

I have mine like this so it's not pushing the hot air from the rad over the rest of the system, this was when I was running 1x vega, 1x rx560 and 2x rx550. I have since put the 550's in my mining rig and populated the 550 spots with itx 570's:
