4790k overheating at default clocks?

[thegr8anand]

I assembled my pc yesterday and its running fine. But when i tried to run AidaExtreme for a few mins it showed that the CPU was throttling. I stopped it and tried OCCT and within 3 mins it stopped because it crossed the 85 deg limit.

 

I have Hyper Evo 212 installed and the ambient temps were 25 deg. The Cpu was normally running around 38-40 deg. I didn't check if the EVO was running at full speed. I thought it was be automatic.

 

What could be the reason and what should i do?

Are you sure that the temps are correct? have you tried verifying it with an other hardware monitor.

Try re mounting the cooler, it might just be on incorrectly.

set a manual voltage because haswell runs hot and if its set to auto it will use more voltage then what it actually needs.

 

also the evo its pretty low tier for a cooler my h80 ran around 80-85 degrees at 1.28 volts

that is really super high for a H80 wow are you sure your not looking at fahrenheit

was thinking the same thing lol

95 degrees at 1.35 volts  those are of course max temps average operating temps are more like 70-80, idle was around 40-50 in push pull.

with this h220x installed temps dropped by 10-15 idle and 20ish full load barely hits into high 60s now

i would think the H80 would get better temps.....ive never had one, i bought an H105 when i got my 4790K, temps are really good

Evo should be fine for 1.27-29V.

 

To OP, try remounting cooler. It looks like your idles are bit over what EVO can do. Also if you are running everything at stock, check on CPU-Z how voltages are doing. I've heard that some mobos raise voltages too high for what load needs.

Ok just took the cooler out. How does this look?

I use more on my coolers. After lifting I have about same amount on both CPU and cooler.

You don't want to use more than a small pea size or it just leaks in the socket pins.

You don't want too little either or it doesn't cover whole thing.

That doesn't matter >.> Most paste spread easily these days unless its Artic silver garbage

Didn't mean that. Too little means some of chip is left with too thin layer -> too little contact surface. Like I said, I've taken my cooler off multiple times (not even reapplying paste) and there has always been about same amount of paste on both sides. Nothing special happening in terms of temps. This with 3 different coolers including my own U14S and 212 build for friend.

At 1.39v about 80deg under load

You have a heatsink mounting issue. That is a lot of thermal paste. I apply a very thin layer of thermal paste using razor blades with neurosurgeon like precision.
