4690k hits 100*c

[huffislost]

hey guys i need some help.  as the title says my cpu is hitting 100* Celsius, and its how quick it hits that worries me.  I was going to overclock my cpu today, so i decided to do some benchmarks, and stress tests to get a baseline.  Once i start up prime95 my cpu temps skyrocket so quick, literally they hit 100*c within 5 seconds.  Ive used multiple temp reading programs to make sure i wasnt getting a mis reading.  So i dont know what to do, i feel like somethings wrong, it just shouldnt be getting that hot, that quick.  My computer is lacking when it comes to cooling, but i didnt think it could make it this bad..  i guess ill list my build so you know what im working with.   -intel 15 4690k, 8gb of corsair vengance ram, asrock h97m motherboard, evga gtx 960 ssc, evga 430w psu, etc.  stock cooling completely

any thoughts? thanks guys

1. Is your CPU cooler on all the way?

2. Are you using thermal paste?

3. Have you ever removed the cooler then put it back on without replacing the thermal paste?

4. is the CPU cooler plugged into the CPU fan header on your mobo?

Reapply some thermal paste may help but seriously pickup an aftermarket CPU cooler if you're attempting to OC. Unless ofc you like housefires.

Only use Blend in Prime95.

 

Small FFT's and Large FFT's will bring you to 100c+ with Haswell chips.

Is it overclocked at all? Even my 4790K is fine with the stock cooler at 3.5GHz.

1) dont use prime95, use intel XTU

 

2) is your cooler's fan running?

 

3) buy a better cooler or turn down the voltage

[Drunk Muffin]

You're using a H series motherboard, you probably won't be able to overclock the CPU very far without an unlocked multiplier. If you are serious about overclocking, invest in a Z series motherboard and a decent cooler. 

For your issue at hand, check to see if your cooler is mounted properly, and check to see if the thermal paste is applied correctly. 

[huffislost]

yes cooler is mounted fine, has never been taken off sense installation and it had the pre applied thermal paste.  im not too serious about overclocking, it was my first time dinking with it.  once i do a case swap in the next month or so, im also going to throw a liquid cooler in it, then ill probably try to OC it a good amount

[huffislost]

just used blend in prime95 instead.  helped a little, highest it got was 86, which i still obviously dont like. but its not as bad as 100.  also on realtemp its showing thermal status of each core, 2 of them say "ok" and other 2 say "LOG" in bold red.  any idea what this means?

Stop using Prime. No reason to with Haswell when you can use something like Intel XTU (has built in OC features so you don't need to bounce to BIOS to test adjustments)

 

What is your voltage at? If you're using auto voltage and Prime that is the source of your problems.

Prime95 is still a viable program to use for stress testing. The only problems some chips have with it is when running small/large FFT's, and the temperature skyrockets for some reason. But blend works just fine.

 

And fyi, Aida64 > XTU for stress testing.

I never said it wasn't a viable program for testing. In this particular case, where there was no mention of voltage (probably left on auto), OP might as well be rolling dice as to when the voltage will spike. There are far better options for stress testing that pose little to no risk.

 

AIDA64 certainly has better monitoring software baked in, as far as the actual computational load placed on the CPU vs. XTU I have no idea which is more rigorous. Both will cap my OC out around 81C after a few hours, and both will crash an unstable system. XTU can be more useful to someone who's just starting an OC test because they can change settings on the fly, which you can't do in AIDA. AIDA's free trial also runs out in a week, XTU is free.

You may be able to improve temperatures a bit if you can lower your ambient temperatures and improve airflow with better-positioned and/or more case fans, but overclocking and stress testing with Prime95 on stock cooling cannot be expected to work very well. Some people can squeeze a few hundred MHz out of a stock-cooled Core i5, but you can't really be surprised when it doesn't work out.

>implying i'll be using the free version

 

I have Aida64: Jack Sparrow Edition. And for testing stability/temps, Prime95 works fine. As long as you use Blend. The only time people run into issues with it, is as i stated before. Small/Large FFT's cause the temperature to skyrocket. It's the chip which is the problem. Since it only became apparent with Haswell.
