i7 3770k Stock Temps

[sanzen07]

I just put together a new machine with an i7 3770k, Cooler Master Hyper 212 Evo, Intel DZ77GA-70K and 16GB Corsair Vengeance Low Profile RAM. I feel like my temps are bit high on the CPU. I used Arctic Silver 5 and just put a pea-sized amount on the processor. Everything is running at stock speeds and I have disabled TurboBoost. I am idling 35-45 degrees on each core and load goes up to 60 degrees. Core 0 seems to be highest and closest to 45 while Core 1 is a little lower. Core 2 and 3 appear to be even lower (<40) and about the same temp. Is this normal? Should I try removing and re-applying the thermal paste?

I've read, but not verified myself, that AS5 has a lengthy curing time and that temps will actually drop by a noticeable margin during this period. You didn't say exactly how long your computer has been running but it seems like it might be pretty fresh. I'm not commenting on your temps either, but you may want to give the AS5 some time before making any decisions. You can find more details on this at the Arctic Silver website.

 

[sanzen07]

Okay, maybe I should give it some time. It's been running for a few hours now.

 

[balane]

I'm sure they recommend some type of power cycling, heating/cooling procedure for that TIM. You might want to give their site a read if you're looking for optimal results. It couldn't hurt to follow their guidelines.

3770k @ 3.7 + AS5 + PHANTEKS + 24 AMBIENT = 48 C in full load

you could buy AS5 and a nice cooler if the temps bother you ...

If you search through recent threads to this forum, you will find that the i7-3770K and similar CPUs have a slightly hotter profile than the Sandy Bridge cores.

There is an issue regarding the choice and use of a TIM (thermal interface material) between the processor cap and the processor itself.

Some folks are attempting to remove the processor cap and replace the TIM with something better. I've seen that some folks are using (or intending to use) IC Diamond.

Since this may be a risky procedure or invalidate your warranty on the CPU, the other option is to wait and see if Intel corrects the problem themselves either with later production runs or simply new steppings in which the TIM factor is also improved or corrected.

From what I've seen for others using IB "K" processors, there may not be anything unusual about the behavior of your own unit at stock settings.

Agree with balane about AS5 needing time to fully set in.


Try running some prime95 to get some heating and cooling cycles. I don't think it should take more than more than week to get the real temps.

Overclocked to 4.5GHz with a Sandy i5 I get around 70C load. Not overclocked, I donno, I don't run non-overclocked

So I guess it isn't that bad. These chips can withstand a lot.

Your load temps are fine, but your idle temp is a bit high. I'm not sure why you turned off turbo - I wouldn't be surprised if in the process you shut off power-saving. Just leave everything at stock - I'd recommend clearing the CMOS to make sure.

It's a known fact that one core will run hotter at idle on the 3770k. It certainly does for me (core 0). This is NOT the core that gets the hottest at load, so it's just a quirk with the 3770's design, not a problem with the cooler installation or TIM application.

Temps look fine to me

I have the same exact CPU and cooler and my max is about 47C load from what I can see. Idle is in the low 30s. Is there good airflow in your case?

 

[sanzen07]

I turned off Turbo to see if it made any difference in the temps. Power saving is not disabled.

I also took off the heatsink, cleaned it and re-applied AS5. The AS5 was not spread very well as I could tell when I took off cooler. Temps are little bit better now but not by much. I have good airflow in my P183 case with 4x 120mm Scythe case fans (2 front, 1 back, 1 top). My Core 2 Duo E6600 used to idle at 25-28C in this case with same configuration. The case is also virtually dust free as I cleaned it thoroughly before putting the new board/CPU/RAM in. Why would my temps be so much different than yours with same CPU and cooler?

Here's my Core Temp output after having it on for a few hours - room temp is about 80 degrees F:

You're wasting your time. Those are perfectly normal temps for IB

assuming both rooms are 80f mobos make a difference.

Not sure why everyone thinks that. Been using the stuff for a long time and never had this issue.

Temp are fine.

 

[coffeejunkee]

Sure, but it is a bit strange core 0 is the hottest, unless you're using the igp.

That's how the 3770k works.

 

[Ferzerp]

That's how the 3770k works.

Core 0 is always the *coolest* because the igpu acts as a directly attached heat sink. Core 1 is warmer, Core 2 is warmest, Core 3 is typically slightly cooler than 2.

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

 

[sanzen07]

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. Maybe I am not putting enough thermal paste? I used about a pea-sized amount on the processor. The first time I took the cooler off and replaced it, the paste had not covered the entire area of the CPU.

 

[Termie]

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.

 

[2is]

Surely if you're that bored you can do more exciting things than attempt to fix a problem that doesn't exist?

 

[Phynaz]

Repeat:
Your temps are fine!

 

[sanzen07]

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