CPU Fan

[Bradforth]

Hi all,
Phew....some very interesting comments on this subject regarding CPU cooling, I have only fitted this CPU (4670k) earlier this year and only O.C the rig about a couple of months ago so I may now look at a better cooler before it's to late.
I used the Asus automatic O.C facility to make the adjustments which is considered safe.
Using the Asus facility if any of the hardware goes over the safe margins relating to temps then CPU automatically resorts back to the standard stock frequency, this has never happened because it would have recorded this on the software below.

I use the software OpenHardwareMonitor to record all temps etc, even last week during the heat wave the highest temp recorded was 65c, no heat was coming from the case vents and my system was/is stable.

Just to give me something to think about could someone give more details on a suitable air cooler to use, not sure whether this is relevant but my M.b is a Asus Z97-k.

Regards,
Pete.

The Coolermaster EVO is widely regarded as being one of the better 3rd party addons, certainly affordable at around £30

72c is a temperature of the CPU metal case, not the cores themselves...

...but is the only indicator of how hot the thing is getting, so for all intents and purposes it's taken as the temperature of the CPU and a clue as to when/if the user needs to add extra cooling.

This is not the way I meant it.

Rockdoc above me says:

"Given that 72C is Intel's safe operating temperature for this series of chips..."

72C Intel speaks about in their specifications is the Tcase value, the temperature of the metal case, not the temperature of the cores we all see in the temp measuring apps.

Just a piece of advice to anyone thinking of fitting an aftermarket heatsink/fan to make sure that there is sufficient clearance in your case, some of them are pretty tall and can foul the side panel of a small, narrow case. Also a few come without fans and you have to supply and fit your own.

Regards,

You are correct Pentiums run much cooler than IvyBridge or Haswell (as does SandyBridge).
Good to hear that the stock cooler is working well!

thanks for the responses!!
Its ironic to think that it was Intel themselves rather than a stock cooler that caused overheating of IvyBridge cpu's (possibly Haswell) when they changed the thermal compound (cheaper??) that sits between the cpu die and the lid. SandyBridge cpu's used a different compound and did not suffer with this problem.

This caused great consternation in the FS FSX world with thousands of simmers removing the lid (one guy seemed to be using a hammer and chisel) lapping the die with lapping paste (nobody seemed to lap the lid) replacing the thermal compound (the variants recommended were legion) and then putting on a super duper cooler. The "emperor's new clothes" mentality seemed to indicate that this process was a great success and FSX never looked better. I stuck with my old standard cooled oc'd Sandybridge and sat back and watched all the excitement and palaver! It's still going and Ts2015 never looked better! Hindsight and a patronizing demeanor (of which I have oodles) helped of course!

Actually Sandy bridge CPUs were soldered and did not use any thermal paste. Intel started to use it with Ivy bridge, which caused significant increases in load temperatures.

The following article from 2012 was one of the first that confirmed it:

I am pretty sure Haswells have the same issue.

Thanks for the explanation, I should have said SB cpu's did use a different compound ie solder.
I remember one simmer asking how to delid a SB cpu and the preferred method was using a blowtorch.
I don't know if that method worked.

The stock heatsink/fan should do ok if you are not overclocking. But if you really want it to run cooler and/or have a quieter fan then I also recommend the Cooler Master Hyper 212 EVO.

I think to see real difference in your cooling you need to look at the complete package (as mentioned by others). I run with a Corsair h100i water cooler and Corsair fans (2 for the h100i, 2 120mm and 1 200mm for the case and 120mm exhaust). Rarely see CPU temp over 60C.
