4770k Core i7 running way too hot...

[Silver47]

I bought a 4770k last week and so far I love how well it performs in Blender and Premiere, even compared to the 4690k I previously used. I know these badboys are notorious for running very hot, but I think I scored a particularly bad performing one.

Long story short: I'm using the same cooler as previously with my 4690k and the temps are outrageous. If I start Prime95 at stock speed, the temps immediately jump up to ~90°C on the hottest core. My 4690k never went past 62°C with the same setup while being overclocked to 4,2 Ghz. A bad mount is debarred, I've reinstalled the cooler multiple times now with the same outcome.

 

Are these temps to be considered normal?

what cooler?

1. Is it overclocked?
2. Cooler?
3. Thermal Paste?

[Imakuni]

Did you remember to keep voltages the same? It's likely that the 4770k is just drawing more voltage.

 

Outside of that, the TIM was pretty terrible on Haswell chips, took the, Haswell-R to kimda fix it. Delidding would be a great way to get some lower temps

Scythe Big Shuriken 2 Rev. B with beQuiet! Pure Wings 2 PWM fans installed. Like I said, the same setup kept my 4690k at very reasonable temps. I also tested a Corsair H45, kinda got me the same results...

no, like I said, it runs on stock speed with stock voltages.

Arcitc MX4, same as with the 4690k

i5 vs a i7 is a big difference in potential, get a better cooler, your cooler is a low profile cooler.

Didn't properly read the OP, LOL

Arcitc MX-4 shouldn't cause issues. I use it as well and I get amazing CPU temps

you *did* replace the thermal paste, right?

[Kommanche]

Sounds like a candidate for delidding!

Potential is actually the same on P95 small FFT, it's just that HT wastes more energy trying schedule stuff (to no gains, however).

...i was thinking on real life usage especially longterm, OP should get a beefier cooler and push that i7 to 4.5 ghz. 

[Pauleh]

What P95 version? To compare to others, use the "balanced" setting on prime95 26.6. It's the version and settings most people (are supposed to) use to accurately benchmark a systems cooling performance.

Wastes....No gains....wat.

It needs to be, since I have a SG05.

It's exactly that. HT increases pwer consumption a bit while trying to squeeze more performance out of the chip; unfortunately, there's no benefit to it, so the energy ends up being wasted.

[Simon771]

Your only hope is to delid it.

Thank Intel for not soldering it to IHS.

@Hunter259 @Pauleh @nerdslayer1 @Imakuni @PCGuy_5960 @Kommanche thanks for your answers and/or proposed advice guys, but all I asked for was somebody telling me wheter or not those temps are to be considered normal for a 4770k.

Wow. That is so wrong it kinda impressive. 

That shows in games the i7's absolutly crushing the i5's in gaming.

That shows a rendering situation where the i7 runs away with the lead with nearly double the performance.

Are you sure it's getting airflow? Have you reset the bios? Have you checked to make sure the voltage is actually stock? Are you using AVX instruction version of Prime 95?

You have no idea what you're talking about.

Seems if you bought that CPU used, it may have just poor IHS Thermal past at this point. Probably need a delliding. That is not normal stock/stock full load. Also, have you tried AIDA 64 as a stress test instead? P95 seems to be having some issues if not set up properly. Normal stock/stock with LP cooler should be in the 70's from my past experience

Read my posts and the context in which I've written them and you both will understand what I'm trying to say here.

If you're not paying attention to your CPU and are just letting it do it's thing, yes, those temps, while too high for comfort, are normal. If you are taking care of your CPU, however, then there's a problem, hence why each one of us is asking / suggesting difrerent things.
