i7 3770k Stock Temps

[coffeejunkee]

At idle, which is what the OP is concerned about, core 0 is far warmer than any other.

It's not, at least not for me. Idle, temps are the same for all cores (around 30). Only under (heavy) load do I see a difference of around 10-15 degrees between core 0 and the others. So I ask again, is the igp being used?

Okay, over and out. Everyone can stop replying to this thread now.

If you don't mind, after the Prime screenshot I think your temps are high indeed for a stock clocked chip with Hyper 212. I have a better cooler, but under Linx (which causes significantly higher temps than Prime) I stay under 60 degrees. I assume the fan on your cooler is running at 100% during Prime?

I do know you need to apply thermal paste differently for these direct heatpipe contact coolers. Better to apply it to the cooler itself, filling the gaps between heatpipes as well.

Under 60C load with IB? On air? I'll believe that when I see it.

No, I'm not using the IGP. I have disabled it in the BIOS.

I have re-applied thermal paste several times and it really hasn't made a whole lot of difference. The cores seem to be more even now in terms of temperature but temps are about the same level. First time I tried a small bead in the center of the CPU. The second time I tried a bigger bead in the center of the CPU. The last time I tried spreading a very thin layer on the cooler itself and then applying a vertical line on the CPU. The Hyper 212 Evo seems to always be running at around 550RPM even under prime 95 load. Same with my case fans. I have fan control set to auto in the BIOS.

Well sorry, cba with a screenshot right now. But yes, stock i5 3570K hit 57C on the hottest core after 5 runs Linx. HR-02 + TY-140 fan and casefans at 100%. Ambient 20C. HT might add a few degrees ofcourse.

Ok, last method is best for direct touch heatpipes. Seems the mount is ok but your temps are higher because your fan is running at minimum speed.

I run my fans at minimum and my cooler remains cool to the touch. Probably has nothing to do with it.

I'd also like to see proof that you have a calibrated temp < 60v running linx. Although you have disabled HT, so...

He actually doesn't have HT at all. He has an i5. Not sure how he can come to the conclusion the OPs temps are too high. He's comparing them to his own but he has a naturally cooler running CPU and a better cooler so I'm at a loss as to how he can come to that conclusion with this apples to oranges comparison. Not to mention His ambient temps are also 12 degrees F cooler than the OPs. That variable alone would make his temp comparison worthless. As it stands, manufacturing process is the only thing these two configurations have in common.

You can compare just fine. Just keep in mind 3770K runs 100Mhz faster and has HT. That said, I'm just wondering why his temps are rather high, although nothing near problem levels. Answer turned out to be simple, his fan is not running at full speed. How you can say fanspeed doesn't matter is beyond me, ofcourse a cpu will stay cooler if the fan spins faster.

Still no proof huh?

They arent rather high. Therein lies the problem with your flawed comparison. Now you can stop wondering.

Since we're on the topic of ivy stock temps, I though someone may be able to answer this. Is ivy bridge supposed to run hotter than sandy at stock speeds? I mean the i7 2600k has a tdp of 95W, while the comparable ivy, 3770k is 77w, shouldn't it theoretically run cooler (w/o overclocking)?

Not really. That's a common misconception. Heat produced is not the something as how hot something runs. IB runs hotter but actually produces less heat. This is due to the smaller surface area of the die. Think of a heating vent vs a flame from a lighter. The flame is way hotter than the air coming out of the vent but the vent produces way more heat.

Sigh, i'm not trying to brag or whatever you're thinking. At stock frequencies Ivy just doesn't get that hot. Especiallly with a giant cooler and plenty of airflow. Actually, right here in this thread is someone with an i7 3770K with load temps of 60C in IBT (which is pretty much the same as Linx):

For general use, I run mine at 3.9GHz/1v and my load temps in IBT are 60C.

So why wouldn't an i5 3570K at 3.6GHz under a big aftermarket cooler not be slightly below 60C? In case you like to hear it: yes, it can get very hot when overclocked.

Okay, I ran prime 95 for about 6 minutes and my temps are up to 74C max. That seems quite high for a stock clocked processor from what I've been reading across the 'net.

They arent rather high. Therein lies the problem with your flawed comparison. Now you can stop wondering.

Apparently I'm not the only one wondering. But all this is a waste of time. Notice I was the only one asking if the fan on his cooler is actually running at full speed. Turns out it's only running at 500rpm. I don't really understand why there must be arguing over this. Ofcourse you get higher temps than others with fans running at 1600rpm.

Following up on the reference above, here's an IBT run with my 3770k undervolted:

I'd highly recommend anyone who's running close to stock to give undervolting a try - it really does take the heat issue out of the equation.

And props to coffeejunkee for figuring out the problem (even after I suggested there wasn't one) - the CPU cooler fan was running too slow. I'm actually shocked that it didn't heat up more under load, but I guess that just goes to show that stock-clocked IVB CPUs don't get that hot.

Just a quick follow-up, though - my core 0 runs way hotter at idle (~8C - you can see that in the minimum temps), but clearly isn't the hottest core at load. That's why I think the concern people have about a single core being hotter on IVB is blown out of proportion. If it were a problem with the heatsink installation, it would show up both at idle and at load.

Seriously, it's fine. That is exactly in line with my load temps and everyone else who has a 3770k and has posted in this thread.

If you're than concerned about temps, undervolt the chip. For general use, I run mine at 3.9GHz/1v and my load temps in IBT are 60C. I'm sure you could drop that vcore by at least 0.1v using a negative offset in your BIOS.

Looks like you have an engineering sample - not sure how you got one of those, but it may perform slightly differently that a retail chip. Even so, as I (and everyone who actually has a 3770k) has said, your temps are fine.

My 3770K reports as an (ES) in coretemp also. I had assumed this was just an error in the program as the chip is recently released (I also use rc3). Do others with a 3770K have coretemp report something different?
