So i bought a new h100i and the prolimatech pk3 thermal paste cause i do not like the stock ones, i do not trust them. I open the prime 95 v2664 i think, and after 5 minutes it reached 55 celsius on stock speeds. I was pleased cause with the tock cooler it went straight to throttling so i palyed far cry 3. After a couple of hours my temps were 57 at max. Is this nirmal? Are not the temps a little too high with stock volts and speeds? And the thing that surprises me the most is that far cry's 3 temps are in par with the ones in prime 95, which in theory should be a lot higher cause it puts unreal stress to the cpu. Any opinion would be nice.

You're very welcome.

I understand that you're aware of the version issue with Prime95, but as many other Forum Members and readers lurking in the background are misinformed and have many misconceptions about temperatures, I always appreciate an appropriate opportunity to get the word out.

Even though those temps are a bit high there still well within safe operating limits. Have you tried reappling the thermal paste? Did you try running Prime95 for a longer time? I have the H80i and my max temps on Intelburntest got to about 62C but gaming for hours on end my max temp is at the highest is 53C (typically <50C).

That's kinda of weird for P95 and gaming temps to be the same. What monitoring software your using & what's your Vcore and clock speed under load?

I have a swiftech H240-X CPU Liquid Cooling KiT and runing P95 for 5 mins at 4.5Ghz my max temps is about 65C and gaming hardly breaks 50C.

Lol, you're good.

haswell chips throttle around 90c. Anything between 40 and 60 is considered normal without load. Temps in the 70's are considered acceptable under load.

Also, this question has been asked a billion times. Google, or search Tom's, before you post.

57 is still perfectly within the safe range. You really only need to start worrying when it gets above 80. It's possible that you are running far cry 3 at full CPU load, thus giving you the same temps as Prime 95.

Your temps look slightly higher than usual though. I assume you applied your thermal paste correctly and have good case air flow? What are your idle temps?

It is a fa t that i may have put more than enough thermal paste but i did not have the time to redo it. It does not matter how much i game, it does not get past 57C. Howevr i must note that i run the stock h100i fans at about 40% when the temps are 50C.

So i use the HMWmonitor for my temps and it says that my vcore is 0.928 if i remember right.

Yeah i know they are safe, but i thought it was too much. I have searched most of these posts, but i wanted a live conversation with some of you guys and check your thoughts especially on my case.

I use the same software and that can't be right. You're looking at the wrong thing.

My idle temps after about 30' from start up are about 27C and ambient is about 20C. I might have put slightly more thermal paste than needed. My case is an enthoo pro and i have 2 fans pulling in the front, one pulling from the back and the 2 top exhausting (i was trying to achieve positive pressure in my case).

my cpu Vcore is the one on the top below asrock extreme 3 in the voltages section, right?? And sorry for being late in my responses.

No that's not the Vcore you should be looking at. It should max around 1.26-1.275 according to your VID

here is an example of mine's @ 4.5GHz after playing some Battlefield.

Guys,

The reason why there are so many conflicting reports of different temperatures, is that everyone tests their rigs with different stress tests, clock speeds, Vcore, coolers, ambient temperatures and measuring utilities that read two different types of processor temperatures.

Add to that the fact that almost no one bothers to look up Intel's specs, which aren't written to make any sense to anyone anyway. Then there's the term "load" that gets tossed around like gorilla poo in a cage. Load? Which load? What load? Load is a very subjective term.

Applications, rendering, encoding and gaming are partial workloads with fluctuating temperatures, and aren't suitable for thermal testing or comparing temperatures, but they're great for endless debate. Add a graphics card that recirculates heat into your case, and your perspective is lost among all the variables.

The only way to make sense of this mess is to test your rig using a methodology that reduces the variables to the lowest common denominators. The Intel Temp Guide explains how to do it in Section 12 ... yet as the saying goes, you can lead a horse to water, but you can't push a rope. :D

Please read this Tom’s Sticky: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

Use only Real Temp to measure your Core temperatures, as it was designed specifically for Intel processors: Real Temp - http://www.techpowerup.com/downloads/2089/real-temp-3-70/

Use only CPU-Z to read your Core voltage: CPU-Z - http://www.cpuid.com/softwares/cpu-z.html

Always state your ambient temperature. Standard Ambient temperature is 22C, which is normal room temperature, and is the reference value for Intel’s Thermal Specifications. You can't make any valid temperature comparisons without knowing ambient.

Thanks,

Your temps seem perfect! So my voltage is 1.261 as i can see. I thought it was too high that is why i did not take it into acount. What programms do you use for stress testing? Yesterday i used the prime95 v285 and my temps went at 90s! Do i do something wrong in configuring the tests? for example i stress all cores and all threads, is this wrong?

Ok, with the realtemp i get the same results as with HWMonitor. My ambient at that point was about 20C. Today that it is around 14C my idle temps are 19C. Still, after 2 hours of far cry 3 i get 57C. no more, no less. It is like stucking there. In prime95 v266 i think in small fft's i get hardly 60C with 20C ambient, the same as OCCT. In prime95 v285 small fft's i fot 90C with 25C ambient. I heard that the best prime 95 is the v266 and not the v285. And i am thinking to myself, that if i overclock my cpu and test it with prime95 v285 it will go straight itno throttling. So, for now i am planning to resit the block and re-apply the pk3 and recheck if anything improved.

Well my cooling is a bit better than an H100i. Don't use the latest version of P95 stick with V26.6. I do 1HR of OCCT for stress testing. As for your voltage, check your bios and see what it says your Vcore is. It should be a little higher than your VID.

Ok thanks a lot! Your temps seem very good, how come you have not OCed your cpu more? Don't youwant to put more voltage in it?

Guys,

Do NOT run any versions of Prime95 later than 26.6. Here's why:

Core i 2nd, 3rd and 4th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95, such as 28.5, run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces unrealistically high temperatures. The FPU test in the software utility AIDA64 shows the same results.

Prime95 v26.6 produces temperatures on 3rd and 4th Generation processors more consistent with 2nd Generation, which also have AVX instructions, but do not suffer from thermal extremes due to having a soldered Integrated Heat Spreader and a 35% larger Die.

One more thing. On RealtTempGT my hottest core is about 10C higher that the cooler, even on small load ( between 5%-10% ). Is this normal?

I was aware cause i made a mistake and did not know about it and my cpu went straight into throttling and i am a lucky guy i did not fry my cpu (it ran for a minute or so and i was scared to death with it's temps)

Deviations in sensor accuracy between individual Cores may be up to +/- 5C which is Intel's specification. This means there may be 10C between the highest and lowest Cores, so your processor is at the edge of the spec.

"Average" Core temperature is often a more realistic indication of Core temperatures.

RealTempGT does not have an average, does it?
