I don't know why I even bother visit this site... <blockquote>Supports trusted computing: Yes vs No</blockquote> And then at specifications column: <blockquote>Supports trusted computing: No vs Yes</blockquote>

Alright thank you i feel better yeah i dont oc is just when i play game is 70C my idle temp is normarly betwen 30 to 40C depend of the temperature in the house

mark wood (04:22 PM, July 17, 2016)

Same as you only I have two fans pulling air out the top of case as well. It all depends on what you want to do, if overclocking you could probably use more cooling but 70c doesn't sound that bad. Heard their are some bad batches out there, folk that have them are getting really bad temps but yours sound ok, when it hit 90 you can panic :-)

Elkethus Degrace Lauzon (04:13 PM, July 17, 2016)

ah ok i have 2 front fan and 1 in the back + h60 cpu cooler but only have 3 fan do you think i should put 2 more on the top?

mark wood (03:48 PM, July 17, 2016)

Sounds ok . . . got big Zalman heatsink on mine plus 5 case fans . . . it all helps

Elkethus Degrace Lauzon (03:37 PM, July 17, 2016)

i got the 4790k but my temp while i game go to 60 to 70 is it normal?

mark wood (08:36 AM, July 17, 2016)

I have the 4790k, when gaming it hit 4,4 Ghz straight out the box, running really cool, can't seem to get it above 55c . . . Haven't needed to overclock but feel it should hit 5 Ghz no trouble . . . recommend to anyone

Elkethus Degrace Lauzon (06:01 PM, March 26, 2016)

I want to get 1 of those 2. The problem isidk which 1 i dont plan to overcloak but i see that the speed is a bit faster with the K per default but does it wortk 80$ difference price? in my country is expensive like that yes. for 80$ difference should i go with the 4790 normal if i dont plan to overcloak?

HotAsIce (03:32 PM, December 6, 2014)

The 4790k have a higher clock speed ... yes the 4790k is faster ;D

T (09:34 AM, December 6, 2014)

So is the 4790k faster than a 4790 even without overclocking it?
