5820K too hot?

Hi guys

I currently have my CPU overclocked to 4.5ghz and successfully ran a real bench for 15 minutes on various occasions. The only issue I have is that my 5820K seems to run very hot. I use Real Temp to monitor the the temps and It states that I am getting about 85-90 degrees. Below is my overclock settings:

Cpu strap: 125 x 36 = 4.5ghz
uncore: auto (4.12)
pwm phase control balanced
voltage: auto (around 1.25v)
XMP: off
everything else on auto.

I also reseated my cooler (corsair h100i gtx) with fresh artic silver 5 (line method) which made no difference to temps.
Some have suggested that my CPU is too hot and I should RMA it.

What do you guys think?

Any help appreciated

Chris
 
What are your ambient temperatures? What temperatures when gaming? Fan speeds on the h100i radiator? Push or pull? I suppose under normal usage; e.g. gaming, the temperatures do not go as high. Stress tests tend to heat up the cpu lot more as they are designed to do so.

Also I notice that your voltage is set to auto. How you are monitoring the voltage. Better set it manually and run the realbench.

Can you check the cooler pump and fan connections. Do you have the mobo cpu fan settings set to a fast enough limit. Does the H100 sound loud?

Hi guys

I have 2 apache fans running at 100% located at the top of the radiator, pushing air down through the radiator. The h100i sounds like its nice and quiet. I have the pump running at 100%.
idle temp around 33 degrees
full load temp 85-92

software used: real bench (15mins), real temp, cpuz
voltage being monitored by cpuz, i have also tried aida64

Hmm, I've got the same chip also running at 4.5ghz.

At work but off the top of my head the settings are as follows:

Cpu strap: 100 x 45 = 4.5ghz
uncore: 3.00
voltage: 1.27v
XMP: on, but with Mem volts set to 1.35v


It doesn;t get over 65c in Realbench stress tests but usually stays around 60-62c

I do have a 360 Predator cooler (using Thermal Grizzy Kryonaut paste), but there is also a GPU water block in the loop
 
I would just say that this is from memory and I would need to double check the settings when I'm back home. Will do so when I get the chance (hopefully tonight, but I have a lifting session at the gym after work).
 
Sounds to me like it's making poor contact. Paste or cooler itself to the IHS. Or the pump itself is not running.

What speed is the pump indicating? Should show in corsair link. Can you feel/hear it running?

1.22v is a low voltage for that chip. Mines at 4.5ghz 1.25. So voltage isn't an issue here.

Very odd. You would normally expect high idle and load temps to be honest. 30ish degrees is not bad at all for a 5820k.

If you run it to 90c. Then stop the test. Do the temps drop back down to 30c straight away or do they take a little while?

Have you tried different monitoring software? Core temp?

Seeing what the actual core's are reading themselves.
 
I only have this one cooler
When it's under full load 85-92
When I stop benchmark it sits at about 40 and takes a while to return to 30.

I'll try core temp later
 
You put in the OP that you have the voltage on auto. That is probably your issue. It is probably upping the voltage too much under heavy load.

Download HW monitor and see what the realtime voltage readout is when stress testing. CPUZ doesn't give you what the actual realtime voltage is i have found (only the VID not the Vcore or something, i forget which is which).
 
I will download that later then and see what voltage I'm getting.
Could it be that my chip requires low voltage for 4.5ghz? And 1.25v is too much?
 
Can you touch the radiator? I would expect it to be at a similar temperature to the CPU if the heat is being transferred properly, if it doesn't feel hot when the CPU reports 80 degrees then either the block isn't mating with the CPU properly or there's a problem with the loop or pump.
 
I'll try these 3 steps when I go home
1. Try core temp
2. Touch radiator to see if it's warm
3. Set a solid voltage, maybe lower than 1.25

Bare with me guys. I appreciate your feedback
