i7 4790k Temps

[MatthewDratt]

Hello there,

 

I am currently running an i7 4790k at stock speeds with an h105 cooler with the fans that it came with and recently just applied Arctic Silver 5 (I had some random BestBuy Thermal Paste on it previously that was getting just a few degrees higher).

 

Under cinebench the temps get to around 75 C max (70-72 avg on Cinebench). Is this fine? I am only asking because recently, when I've tried to turn on my computer, it boots to the BIOS and says something went wrong and asks if I want to reset the bios. Essentially crashing at startup, but it works fine after that. I'm only assuming its the CPU because the fans are pretty loud at startup, but any other ideas for that if its not the CPU then?

I get those temps...

Your CPU should be fine

[CowsGoRoar]

You might wanna get XTU and lower the voltage. I found that many motherboards overvolt their CPU at stock speeds. I had my Z87-A at 1.202V and I lowered it to 1.168V stable and got a 10C difference. Not even exaggerating.

seems kinda high to me. around 65c is the max i can get with any stress test on a 4.6ghz overclock with an NH-D15

 

that temperature is just fine though, not dangerous at all

[Real_PhillBert]

Whats your OC? Clock and Voltage.

 

I get about 75c with my 4.7Ghz @ 1.275v, on my H110.

Haven't messed around with any voltages so I'll try that and see what happens.

 

Currently running everything at stock.

Hijack thread real quick

When you say mobos over volt cpu, HWMonitor Pro shows VCORE (listed under Mobo) at 1.8v though it shows CPU voltage at 1.275 (where I set it to test my 4.8ghz OC). XTU also shows 1.257. I'm NOT pushing 1.8v through CPU right?

[MatthewDratt]

The auto bios voltage was at 1.35v and yeah when I saw that I figured it has to be that. I tried at 1v and it wouldn't open, but I'm currently stable at 1.2v and Ill see how low I can get it at stock. That alone has 1.2v has lowered my temps about 10 degrees.

I don't understand what you're saying. I meant lower the voltage offset on XTU while I looked at the voltage on CPU-Z.

[LogicalDrm]

Sounds like something is wrong in BIOS or you have some onboard switch in wrong position.

[Wildlord12]

Thats fine, my load C is 65-71c while playin games such like BF4, Its really depends on CPU chip, Not all CPU are the same. I got a same cooler and cpu too 4790K..

 

Edit: ALSO! depends temp room, that also affect CPU temp.

[Kryptyx]

First thing I would do would be fixing your boot up problem. Is the BIOS up to date? Try loading default settings and see if that fixes it. Your temps are fine if you really are pushing ~1.25v.

Seems high for stock speed. I don't break 55c at 4.4ghz. Similar setup.

Wow, what voltage are you running at?

[patrickjp93]

My Dad's 4790k barely breaks 48C at stock (though on a custom loop with a quad radiator). Your motherboard is overvolting it no doubt. There are a number of solid undervolting guides online. It's one of the other really fun "overclocking" pastimes. Maintaining stock speeds at the lowest possible voltage should really be regarded with as much respect as shoving clock rates up. Both are difficult past a certain point.

 

I remember when an old buddy dumped Liquid H2 (yes, helium, rich little twat) over his FX 8350 and got the VCore all the way down to .92x and it still kept going at stock (before the temp dropped so low the silicon seized up).

[Janne]

Wow, what voltage are you running at?

1.2 V

[patrickjp93]

1.2 V

That can't be right. What's the air temp of the room? Do you have fans running at max or at highly reduced speeds? It's possibly a bad block mount, but this seems high even for that.

That definitely can't be right I'm at 1.2v as well.

[Jey R.]

Well you have to understand several things.

First and most important thing.

What's your ambient room temp?

What vcore volts you have?

Did you apply thermal correctly?

What fans configuration you have set and what kinda of airflow you have; positive, neutral or negative pressure?
