4790k high temps misread?...

Hi all,

I recently bought 2 rendernodes both having the same specs, 4790k, gigabyte z97m-d3h, gelid tranquilo rev2, and just an ssd and some ram, nothing special.
Both these systems are idle about 25 degrees but when under load (rendering an image for about 3 minutes) they reach up to about 98 degrees,

I also have an fx 8350, when that one reaches 65 degrees (with stock fan) i can feel the heatpipes getting hotter.

I did the same with both these systems and everything feels nice and cool.

Could this be a misread from the motherboard?
The reason i ask this, in the bios it says about 38 degrees idle, when i installed the stock fan it went up to 65 degrees idle and i could feel that cooler getting hotter.

What we did to be sure was we unplugged all the fans and just watched the temp rise in the bios (with the gelid) all the way from 38 to about 60 orso, when it reached 60 in the bios i could feel the heatpipes and the heatsink getting warmer whereas when it was under load in windows and rendering it said the temps were higher but i could not feel anything, everything was still cool.

Seeing as both these systems have this "problem" could this be a temperature misread from the motherboard, also because the bios has 2 modes, classic and standard, classic says 47 degrees orso and standard says about 38 which is odd enough for me (maybe the classic version simply puts more stress on the cpu? i dont know)

I mean all techtalk aside, if anything anywhere gets up to 100degrees celcius, you should atleast be able to feel anything right?

Thanks in advance,


Sabino,...
 
What software are you using to read your temperatures? If it's a single temperature (not 4, 1 for each core) that one is likely coming from the socket temp probe. These most certainly can be read wrong. However the core temperatures are usually pretty accurate. If the socket temp is reading right, it usually reads cooler than the core temps.

i tried coretemp and realtemp.

But how about the physical aspect, i felt absolutely nothing and both of these cpu's having the same problem?...means i bought 2 faulty chips?...
 
Was that with Speccy?

Also have you updated to the latest BIOS for your motherboard. It's unlikely that the BIOS would skew the coretemp readings, but it is certainly worth a shot.

I don't see how you could get unlucky and get two bad CPU's. Bad CPU's happen, but they are exceedingly rare. So to get two would be practically unheard of.

I'm going to ask and please don't get mad, there have been times when I went through a long process like this only to find out the user missed an obvious step or made a misstep.

Did you use thermal paste and how much?

If there was a clear plastic cover over the heatsink base to protect from scratches, did you remove them before installing them?

No, that was realtemp, ill try speccy tomorrow.
My, i thought i had the the latest but apparantly i havent, ill fix that tomorrow also (doubt it would make a big difference but still)

Add Pentium AE G3258 CPU overclocking function, Improve SSD Performance
This is all they added.

Haha yes, i removed the plastic and went for the pea method of applying thermal paste, even tried a different paste, did help a little but not enough,...
 
Sorry, had to ask.

BIOS revision notes are never too detailed. They also tend to stick to the biggest highlight.

I had to look at your actual heatsink as I wasn't familiar with it. I was thinking maybe it used the stupid push pin setup, but it looks like it uses a pretty solid mounting system.

Did you install any of the GigaByte monitoring sofware? If so try uninstalling it and running CoreTemp / RealTemp / Speccy.
