2500k temp readings?

renandstimpy · 14 Feb 2012 at 18:11

I have a Gigabyte z68ap-d3 with a i5-2500k using a corsair a50 cooler. At load (at 4.1ghz) Coretemp reads 78C, easytune reads 65C and touch BIOS reads 67C. Which one is correct? If its coretemp, it seems a bit too high for me. Im not exactly pushing the CPU that much :confused:

Core Temp is usually pretty accurate, the stock cooler would be better than that.
You need to check that the cooler is seated correctly, the pump and fan are working properly and you havent put too much TIM on, just use a small amount, enough to fill the imperfections in the Heatspreader and heatsink faces.

Hes using the A50, The air cooler.

Erm, my 2600k was a little on the hot side with my A50, not sure if the cooler is just bad or it was an error on my end. But try reseating it.

Whats the rest of the cooling like in your case?

This
and what is coretemp saying is your tjmaxx?
I am not familiar with your cpu, but on my old B3 Q6600, the tjmax used to be set at 100, when it should have been at 90, this gave me my temps +10.C higher then they should have been until i corrected it.
also try realtemp

that's interesting i just reduced tjmaxx on my i5 from 100 to 90 in real temp and it brought temps down to what the asus in built temp monitoring software is telling me gone down by about 7c

renandstimpy · 15 Feb 2012 at 18:19

thanks, I'm going to reseat the A50 and position the fan to blow over the heatsink towards the exhaust fan.
BTW, idle temps show 27C TjMax 72

I've noticed this also. I have my [email protected] running prime blend for 30 minutes and am reading different results from the bios and gigabytes easytune software and real temp. Bios and easytune results are pretty much the same maxing out at around 65 degrees under load. Real temp and some others are reporting it around 10 degrees higher. I read somewhere its to do with the z68 chipset and programmes not reading the temps correctly.

Look a lil high to me but I'm no expert by any means. Only just got a 2500k myself. My temps at 4.3 are hitting 69-72c using 5 passes of IBT max(10gb ram). I have the h50 cooler but paste has only been on for about 15 hours.

so does that mean coretemp, easytune etc are all wrong with z68?

Sorry after reading up it was the voltages that were read wrong on the z68 chipset with various programmes. I think easytune reads them right as its the same as the bios. The temperature reading from coretemp, real temp etc I think are right. They read the core temperature whereas easytune and the bios read the cpu temp. That's what I'm lead to believe after doing a little research, please someone correct me if I am wrong.

This is bad for me though as it means running intel burn test has my 2500k @ 4.3ghz temperatures going up in to the 90's according to real temp. I am sure I have seated the heatsink correctly and applied only a small blob of thermal paste to the cpu as recommended on here. I'm using a gelid tranquillo. Could be that I have only 2 x 500rpm noctua fans inside my case and its not providing enough airflow. My case temps range from 38 to 40 degrees. Does anyone else know what I could be doing wrong? I'm willing to get a new case if necessary.

According to http://forums.overclockers.co.uk/showthread.php?p=20659055 the tjmax on the 2500k is 98 degrees core temp. I'm going to try putting that figure in to real temp and see what it comes back at.

Are you using low noise adapters to reduce those Noctua's to 500 rpm?
I run my Noctua's at a higher speed to shift more air but the noise levels are still very good.
More throughput of air can only help.

Hi Menty. I'm not at home at the moment so can't check. I think they are max 500rpm, well that's what's always reported in the bios and I have never seen them go higher. I'll have a look when I get home tonight. I've just ordered the noctua NH-D14 cooler so I'm hoping that will bring down my temps a little.

Hi sorry to hijack this thread again

I've checked out what was wrong. The rear noctua was plugged in to the 3 pin sys1 connector and was actually running at 800rpm which is the full speed for this model fan. The front intake one I had plugged in to sys2 and was running very slowly. This is a 4 pin connector and the noctua's are 3 pin. It wasn't showing any reading for speed in the bios so I have plugged it straight in to 5v via the adaptor and it is now running at full speed. Could I plug the front noctua in to the PWR connector?

My motherboard temps have dropped a bit and running an intel burn test is pushing up the cpu temp to a max 82 degrees but it hovers around 80. This is with my 2500k @ 4.5ghz.

Cheers
