Does Hyperthreding makes my cpu run hotter?

Hi!

 

Sorry, my english is bad.

 

I'm having some troubles with my new i7 4790K. Temps goes from 25 on idle all up to 75 on heavy load. I have an Cooler Master 212 Evo cooler. I'm not too worried about temps, but the noise of the fans is very annoying. 

 

Does Hyperthreding make my cpu runs hotter? And if i deactivate that, the general performance will be affected in any way?

Mostly no technically make it run hotter. It does make it run hotter, but if you turn it off you really won't notice. If you turn it off, you will lose proccessing power

[gavanorio]

No it does not make it run any noticable amount hotter. It does make it run hotter, but if you turn it off you really won't notice. If you turn it off, you will lose proccessing power

Oh well... Thanks

Yes hyperthreading might make it run hotter, but it will improve multitasking I believe.

It can and does usually make it a few degrees hotter, only really under full load though. ie: Encoding 100% across all cores it will squeeze a few more degrees out of it.

[Briggsy]

not enough to justify disabling it.

At what clock speeds and core voltage are you running because 78 seems mad

[Uphorics]

Honestly those temps are pretty much fine, your CPU is just a tad hotter, but you should only be worrying if it's hitting above 85 or so.

Try remounting your cooler and do a stress test and see if it goes down

Hyperthreading probably does increase temperatures slightly if the extra logical cores are being used, but it would make a much bigger difference to just make sure your case is well ventilated.

 

Especially considering you live in a rather warm place, 75 °C under load isn't really so bad.

Hyperthreading will increase temperatures but not substantially. In everyday browsing or gaming you probably wouldn't notice if hyperthreading is on or off. That being said you did buy the 4790k to have hyperthreading, otherwise you would have just opted for the i5 variant. I would suggest swapping out the stock Hyper 212 fan for a noctua NF-F12 to reduce the noise and just run with it.

[i_build_nanosuits]

Hyper-threading allows the CPU cores to be more efficiently utilized through advanced scheduling of the threads and less ''downtime'' between instructions.
So the CPU is working harder therefore it does consumes a little bit more energy and does run a little bit hotter, nothing to worry about though and it's WELL worth the trade off.

[Humbug]

Under what load does the CPU hit 75 degrees C?

[Gargantua]

At what clock speeds and core voltage are you running because 78 seems mad

how ? will you plz explain ? 78C is just normal for an i74790K with evo 212 on load .

if you are running at stock speed . first of all go in to bios and change voltage from auto to manual and then put it on 1.10V and check if its stable of not then repeat the same untill its stable for 20 mints stress test on Inter extreme tuning utility or Aida64. on auto voltage D.C CPUs on Z97 chipshit gone mad when you put load on them . and voltage claim to 1.3xx+ that is making it hot actually i think. do this and then your temp will be lower and fan will be slower ....

No.It is not viable to turn off Hyper-threading.To your question nature is somewhat partial you might say.Take this.

1.If you disable HT,you won't be able to signify the temperature drop in CPU temp.Its almost negligible!.

   It isn't worth the bother of doing that,in addition you maybe risking potential performance degradation(not by much in real      world),nonetheless!

 

2.On the other way around(Off-topic,non-related):

   Suppose if you have a totally non-HT supported CPU like i5,then it is a bit cooler than i7.

   So it is not just enable-disable hyperthreading,it depends on the architecture of CPU a lot.More logical core=more space,more heat trapping is possible and difficult to cool.Almost irrespective if u enable/disable HT
