Hi all,

I've recently built a new system and I have a question regarding temps of the processor.

I bought the HyperEvo cooler for my CPU and I did find that it was a little loose when fitted. I searched online and found many others had the same experience but they all agreed that it was fine as it was, so I continued.

My idle temps for the 5930k (no oc) is around 50C which I know is probably too hot, but I was first alerted to this issue when running Handbrake. My CPU temps then hit around 90-95C. (measured with Real Temp and HWMonitor)

My question is simple then, are these temps too hot or normal and i'm just worrying over nothing?

I figure I will have to replace the Evo but I wasn't expecting to have to do it so soon.

Thanks for taking the time to read through this.

Ran a quick test again to check the RPM.

At 90C+ it's at 1600RPM.

I plugged the cooler's fan into the CPU fan slot, as suggested by everything I read and everything i've ever been told about putting together a PC.

@CompuTronix all the testing i've done as per your instructions were done to the best of my ability in the ways that the tutorials you gave me stated.

Reading the "Thermal Paste" post you gave me, I believe I have applied the correct amount of paste to the processor. Not too much, not too little.

In your expert opinion, would a thermal paste issue really cause heat changes of over 20C?

Or is it far more likely that it's simply my poor choice in trying to save a little cash, that's causing the issue?

As for the fan. The "EU version" of the HyperEvo 212 has a max RPM of 1600, which is what CompuTronix meant. So my fan IS running correctly at 100% (1600RPM) at temps of 90C.

In my opinion ad as far as i know, a change of 20C is way too much for a thermal paste bad apply...
It could be a faulty Heat Sink, maybe the Heat Pipe are not well done, who knows RMA it after trying the thermal paste reapply.

Tho your answer to my post seems a bit angry, did i offended you by saying above stuff about PIN connection? If so im sorry, i didn't meant to. i did it too as a distraction while back in the days. ahah, let's see what CompuTronix has to say.
Hope you fix it soon, Good luck.

Cheers

EDIT: Im sorry for my english tho, it's not my native language and i may not be understandable as i should, sorry.

Thank you Bafioo, no offence taken, just simply that I know I plugged the fan into the CPUfan header and the fan does run perfectly well. But from all the information I can see the fan does run at MAX 100% when fully loaded. So it is working perfectly well, it's just the heatsink etc. is not strong enough to cool my CPU.

This was a worry I had when I bought it all. So it is my fault. I just thought the EVO would be able to cope. I was wrong

Intake from the front and side of the case. The heatsink fan is facing front, so pulling air from the air pushed from the front fans. Then pushing towards the 140mm at the back. There are two 140mm fans on the top of the case as exhaust fans also.

Your i7 5930K supports memory up to 2133.

Are you running the memory at 2800? If so, then the processor's on-die memory controller is forced to be overclocked, which can create significant heat.

Also, running the memory set to an XMP Profile can also create heat.

OH GOOD GOD! What the hell have I gone and done that for???!!!

I can't believe I could be so stupid. I even remember checking what RAM it would support. I've obviously gone and confused what the MoBo can take and what the CPU can handle....

Oh hell what an ijit I am!

I can't tell you how foolish I feel right now... after all this chatting and testing and i've made such a stupid error!

It's OK ... no worries. 😀 Just downclock the memory and tighten up the timings to the spec's for Corsair's 2133 counterparts.

Give that a try and let's see how much of a decrease we get in Core temperatures. Just for consistency, let's stay with Prime95 v26.6 Small FFT's.

And you still getting those temps huh?

Hmm... still thinking that might be a faulty Cooler.

Try with the intel stock one, and see how the temperatures are. if the same or a little bit higher then im right, the Cooler is faulty

@Bafioo I didn't have an intel stock cooler, I bought the processor without one because I was always going to use an after market version.

@CompuTronix This build is only 2 weeks old and I cleared the CMOS when I built it. I can't see how that would effect the readings. And FYI when I checked the RAM in the bios the temperature read 69C, Mobo 30C. If that helps at all.

Thank you for that information. Just to say we did, please re-check BIOS to see if your memory is running with an XMP Profile.

Concerning CPU temperature in BIOS, you can't depend on BIOS to be accurate. CPU temperature in BIOS is higher than in Windows at idle, because BIOS starts the processor at boot voltage to ensure that it can initialize under any conditions.

There are 5 sensors in a quad core; 1 CPU sensor and 4 Core sensors.

CPU temperature is measured by a single analog thermal diode located under the cores, which is the overall temperature of the entire processor. This value is calibrated to look-up tables in BIOS, and is read through BIOS.

Thermal code can vary greatly between BIOS suppliers and version updates, and can be wrong by up to 30C. BIOS or CPU temperature may not be accurate.

Core temperatures are read directly from the digital thermal sensors in each core, which are factory calibrated by Intel. Core temperature is 5C higher than CPU temperature due to sensor location.

Core temperature is the standard for thermal measurement because it's consistently more accurate than CPU temperature.

We need to know what the Core temperatures are in Windows at 100% workload.

Cleared CMOS and reran the stress test. The temps were the same. 92-95C

I don't have time right now to reseat the cooler. Plus I need the Isopropyl to clean it before reseating. But I will try that as a last resort. Then the only answer, I presume, would be to buy a decent cooler, like the Corsair H110?

I would be carefull with those All in one Liquid solutions... especially from Cooler Master, they are noisy and if they are faulty you could say bye to your first GPU.

As i said before you can easily rely into Noctua air solutions, and if you are not planning to overclock you can go for solutions that are from 40 to 60 dollars.

Like i got a Noctua NH D14 for 74 Euros. it could keep my i5 3570k at 4.8Ghz 1.350 Vcore to a peak of 73C° under heavy stress testing, while also stress testing my GPU, case closed. i mean... wow. And those are unrealistic temps you won't get em by playing Video games or by rendering(Maybe by rendering heavy stuff)

@laviniuc Yes I know that there's a locking knob for the full wide position. It is set fine. Simply isn't as tightly pressed to the CPU as many of the older heatsinks that used to be supplied with processors.

@Bafioo In honesty I really don't want to buy a Noctura, because their colours are atrocious! Yes, i know they are some of the best coolers around but I really don't want a big brown mess in my PC case lol

Before I bought the HyperEvo I did look at the Zalman cooler, if I was going to try another air cooler it would probably be that one.

Goddamnit! i knew it! then check this one http://www.coolermaster.com/cooling/cpu-air-cooler/v8/

tho you can get other fans instead of the original one with the noctua, or you can paint them as i did ahaha

Ah yes, I looked at the V8 when I was buying the parts. But I didn't know if it was really any good. The three top air cooling solutions were the Noctura, HyperEvo and the Zalman. (I forget the exact models)

But that V8 would match my colour scheme perfectly lol :)

Yeah I could buy two SP fans to go with it I guess. I will have a look in the morning. Thank you.

Glad to be helpfull 😀 tho, could i ask you why did you got that cpu? i mean, other than gaming, do you render and stuff?
