I5 2500K TEMPS and prolima megahalems, Some advice wanted ;<

[karkee]

So I assembled my system and did some load tests but I think something is really wrong with me my temps when I compare them to the guy who reviewed the CPU's on guru3d.

Article : http://www.guru3d.com/article/core-i5-2 ... k-review/7

The results above are based on the reference motherboards, reference clock frequencies and the reference stock Intel CPU cooler.
His highest core temp goes around 47°.

My temps with megahalems + scythe PWM fan , used MX-2 also. (Solo case, noctua fan at 500RPM exhaust)

Load I get the highest core 51° the rest are around 47/48°

Either something is really off with his tests or I am doing something really wrong, I reseated the heatsink twice last time I used mx-2 instead of a5, made my temps go down with like 4°.

Maybi I should assemble my setups in another case then solo for better airflow or am I wrong?

:(

[quest_for_silence]

am I wrong?

Maybe you're wrong: anyway, I would suggest you to give a read to somewhat more dependable sources as this one, or this other one (see the hard disk temperature on the Guru3D page: 1°C!).

Hi karkee,

Maybe you have put too mutch MX-2 paste, only the size of a rice grain is needed

I saw one megahelms with a fan keep at 67° a 2500k @ 4700mhz 1.336v at load

[karkee]

Hmm well on that one site he gets 50° with a TRUE, I am getting a little lower temps with megahalems so I guess im more then fine?

I dont used to much mx2 it was fine, like a little rice thingy

[quest_for_silence]

so I guess im more then fine?

It should be so: even HT4U.net has found a load temp of 61°C-78°C with the stock heatsink, so I think Guru3D is plainly wrong.

[CA_Steve]

I wouldn't sweat 4C. It could just be the difference in his case/cooling/fan speeds.

[quest_for_silence]

I wouldn't sweat 4C.

Guru3D is reporting an up to 30°C advantage.

[karkee]

So load temps around 48/50° with megahalems is more then fine right?

Now I just need to play around some with fans (what RMP I want for CPU fan/exhaust), or if im gonna use PWM fan.

...maybe I read the OP wrong...

I am not certain I any longer have much trust in the accuracy of any of these monitoring utilities to be that accurate, especially for clock speed. But even for temps...how do you go about comparing them... its hard to tell where they are getting the temps from (especially speedfan)/ Now it may be that I am just too dense to properly interpret them. But still.

Here is what I have for my computer (an i5 650) currently.

Core Temp 0.99.8
2607 MHz (133x 19.5)
Core 0 = 25C - 43C
Core 1 = 23C - 39C

CPUID Tmonitor 1.03
Core 1 = 1203 MHz
Core 2 = 1203 MHz

CPU-Z
3334 MHz (133x 25)

Speedfan 4.2
CPU temp = 25C - 39C
Temp values for 4 cores (there are only 2 physical cores)
varying from 23C - 40C at any one point in time with a spread of about 5C (and with different cores swaping temp locations with each other at random.

CPUID Hardware monitor 1.17
"Temperatures CPUTIN" = 25C - 41C
Core 0 = 26C - 42C
Core 2 = 24C - 40C

...maybe I read the OP wrong...

No, it's me that I haven't been quite precise: I was referring to the other reviews.

HT4u and Hardware Canucks reported the quad cores may run from 65°C to maybe 75°C at load, with the stock DHA-A heatsink: in the nominally same conditions Guru3D declares those 47/51°C, so up to 30°C less.
Being not quite a small difference - I guess -, I am tempted to think there have to be some error, or a misinterpretation (maybe even by myself) about these latter findings.

[karkee]

Well I just don't know what I should do now, at first I wanted to get my temps as possible so I could tune down my fans for silence... but I just can't seem to find out if my temps are good for standard clock at load with such a good heatsink and I dont think its the solo airflow.

If I search on google most people posting temps are OCing.

[CA_Steve]

I am not certain I any longer have much trust in the accuracy of any of these monitoring utilities to be that accurate <snip>

Well, they aren't meant to be accurate, just repeatable.

Here's a decent explanation on the problem of linearizing temp sensors at Techpowerup by the author of RealTemp.

I recommend running a calibration sequence prior to temp testing.

Quest_for_silence: Ah, thanks. I am less confused. Yep, a 30C delta is definately an outlier. We still don't know the details of the setup - hurricane force CPU fans, maybe.

[CA_Steve]

So load temps around 48/50° with megahalems is more then fine right?

Yes! Mess with your fan settings to lower noise all you want.

Remember, the CPU is rated to run at > 70C. So, if you see 50C while running a thermal load benchmark utility like Prime95, then you are golden.

[cordis]

Yeah, 50C is great, I have an i7 980x with a megahalems on it, and it's hit a max of 53C while running under full load, so 50C is just fine. Mine was spiking into the 80C range until I optimized the airflow in my case, had a little fan malfunction to deal with. I think the max that Intel posts is 100C, but I find anything under 85C is probably ok for most CPUs.

In terms of temperature measurement, yeah, it is kind of a crap shoot. Comparing motherboard manufacturer monitor programs to other tools, I've found that Cpu Temp is the closest, SpeedFan seems to be pretty far off for the i7 980x, I wouldn't trust it on more recent processors.

[karkee]

Though I was really wondering if it wouldnt have been better if I went with another case like P183 or another case instead of the solo... maybi I would get even lower temps or is the airflow more then good enough with the solo?

[CA_Steve]

If we say the temps are good enough three times, do we win a prize?

[karkee]

yes I have a spare I5 2500 want it? but then you must dance nakkit aswell:p

I silenced the PC a little also, max core temp 54, the others 49 and 50°.

[CA_Steve]

but then you must dance nakkit aswell:p

Sorry - this is the USA. I can shoot you, but there will be no nekkid dancing. (ok, cross-threaded humor. sorry)

54C and a quiet PC is a good combination. Congrats.
