Hi!, I am a little confused with all I've read in several posts of this forum.. I also own a i5-4670K and i thought that, under high load, everything under 90 ºC was fine.
First of all i must say I am not overclocking expert and i won't have my PC running games or apps that hit the 100% CPU usage all the time. I just wanted to overclock a little my CPU and enjoy a little better speeds in general and when I game from time to time.
Before my desktop PC i owned 3 different laptops, I used them around 3 or 4 years each until i decided to upgrade to a better one. All of them Intel. The last one a hp with Core i7-720QM. In all these laptops, like many laptops, even in idle cpu temps are about 70 ºC, when i used them to play games they use to go to more than 80-88 ºC and if i played emulators like dolphin for the Wii or PCSX2 for PS2 then they usually went up to 90 - 95 ºC. Then with heatsink cleanning and a cooler the thing improved a little bit. Anyway, what i am trying to say is that this high temps seems almost unavoidable for laptops, and at least my three laptops didn't die yet in 4 years and who wants a CPU for more than 4 years??.
So, are desktop CPU less durable, more weak? or is the overclocking community exagerating a little??.. maybe over 75 ºC is dangerous only if you are planning to be gaming 12 hours per day?.
I am not saying I don't believe what you guys say, just trying to understand.. i am a little dissapointed cause I thought i might do at least a little overclocking with my PC but even at 4.0 Ghz is reaching easily the 85 ºC with prime95 small fft... the thing is that when i play some emu games or whatever is not going so high at all, maybe 60 - 70ºC... Another thing i notice is that always core 1 run way hotter than the others under prime95 and core 4 colder. For example, in stock, without any OC and prime95 small FFT: core1: 76, core2: 70, core3:69, core4:67, almost 10 ºC of difference!
So what should I do??
By the way my specs are:
Tower ----- Zalman Z11 Plus
Power ----- Tacens Radix VI 750W
MoBo ------ Asrock Z87 Extreme4
CPU -------- Intel Core i5-4670K
Cooler ----- Noctua NH-D14
RAM ------- G. Skill Ripjaws X DDR3 2133 PC3-17000 2x4GB CL11
Graphics - Radeon HD 5750 1GB DDR5
I used a predefined profile from the MoBo UEFI to OC it from 3.4 to 4.0 Ghz. Probably this is not the best way.. but i don't know much about OC and i didn't want to spend hours researching as i am a quite busy these days . Also I read some people were fine with this profiles, even the 4.4 GHz profile.
I know its not a big PC config for overclocking but i bought noctua NH-D14 and the Z87 Extreme 4 thinking in at least a little of OC.
Thanks in advance, and sorry if I made mistakes as i am not english speaker...
If it's hitting that idle then you have the HSF seated wrong.
As well i just realized i didnt put any thermal paste on! Which im guessing is really bad? But ok that temp is to high you say. Defiantly going to get a better HSF as well. This my first build ever and i believe i got ahead of myself. This pc is going to used mainly for long gaming sessions. So i would love to here your guys opinion on my build.
