E2180 - 77*C Load Temps - Page 3

post #21 of 59
Thread Starter 
I have some resultage -
Before (3.2ghz @ 1.45v with Big Typhoon) -
Idle - 51*C
Load - 77*C after 7mins of OCCT (I cancelled it because 77*C is as far as I am willing to take it)

With case side open and mains fan pointing in -
Idle - 48*C
Load - 74*C after 7mins of OCCT (still running but is set to cancel at 75*C)

Those temps were highest peaks. It fluctuates.

So not really a huge difference - 3*C off load and idle. What is it? I've run out of things to try .

Hi

Doesn't seem like your case is the culprit. I also have a 2180 with similiar symptoms. Fresh air coming in through the sides didn't help me much, case airflow is good already. I'm thinking mine is a limited CPU/motherboard. I can't even get 3.2GHZ to boot. I managed to hit 3.1GHZ with voltage at 1.55v and temps are in the high 70C's CPU and low 90C's core (under load with aftermarket cooler). Was too hot for me to be comfortable with so thats why i'm stuck at 3.0 GHZ (temps are MUCH lower in the 60C's). Perhaps we have the same limitation with our CPU's?

Perhaps. I am going to try lapping my CPU to see if the IHS is the culprit . Will post back results in a week or so.

Well I've lapped the CPU. The IHS was very uneven with a large concave area directly above the CPU die.
My load temps have now gone down from 78*C to 72*C. I also Idle at 46*C rather than 51*C. This is all at 3.2ghz @ 1.44v.

Heres the best lapping guide I could find (Sorry is an extrenal link but OCN doesn't have much to offer ) -
http://forums.hardwarelogic.com/f32/...uide-8516.html

I can hardly say it was an enjoyable experience, it was very monotonous but the results were pretty much worth it IMO. The temp change could have been alot better but its enough for me to keep 3.2ghz for 24/7 usage . I think the root of the problem is the poor thermal contact between the IHS and the CPU die, but I am NOT going to risk a de-lidding .

This problem has been bugging me since I have had the processor. I had a Freezer 7 Pro on it at first. I loaded at above 75*C (don't know how high because OCCT was set to stop after 74*C) this was with the overclock in my sig - 3.2ghz at 1.425v. I also idled at around 53*C. Bear in mind these are the best temps I could get and I used AS5. I also tried an assortment of AS5 application methods - Line, grain of rice, blob, spread out with credit card. I used nearly half a tube of AS5 trying all these methods. Of which none gave any noticable difference.
So then I thought this Freezer 7 pro can't be up to it. So I managed to get my hands on a thermaltake big typhoon. My temps are absolutely identical to the Freezer 7 pro. I've tried several remounts, cleaned and buffed the heatsink with rubbing alcohol for ages so its nice and shiny. No change at all .

So heres the important bit -
-Is there anything else I can do? - Please don't suggest a remount, i have tried.
-Is it the processors fault.
-How much should I screw down the Big Typhoon?
-Should I just throw caution to the wind and live with a processor that loads around 80*C?

There are no scratches on either the processor or the big typhoon. I am aware of AS5 cure time but thats only a few degrees and even taking those off it would be really high.

This really is a problem I want to sort out because I know this chip is capable of 3.5ghz perfectly stable, the temps just get insanely high and a better heatsink doesn't seem to have done anything.

Please note: I have added 15*C to speedfan load temps to account for the TjMax 85*C debacle.

EDIT: Ambients are 21*C with good case airflow.
Man, that's messed... with the same vCore, my chip hits 3ghz, and maxes at 56 degrees. Can you not relocate the PC to like a place with a window or something so you can open the window and cool the PC?

-edit- it seems your chip was the same or similar to mine. I had to settle for 2.4 at stock and then give her a massive boost in volts to hit 3ghz. What's more, i have the same cooler. I did, however, install a fan and that seems to help the temps... Ummm, Try cleaning up your cables and make sure the airflow's as good as it can be... also try running her with the side panel off. Turn on an AC if you have one nearby. If all that fails, i suggest getting an Antec 900, loading it up with fans, and putting it next to a window... I don't have an antec 900, but removing the side panel and opening the windows has dropped my idle temps once to about 9 degrees in UK winter.

if not, then change the chip and the mobo, or leave the CPU at 2.4...

Hope that helps...

I tried getting a mains fan near the case, it only helped 2*C. I think the contact between the IHS and the CPU die is the culprit, apparantly some batches are botched. Also are you reading temps with HWmonitor - speedfan and coretemp are out by 15*C.

Since you already lapped the IHS, may as well lap your Big Typhoon. Should lower it a few more degrees.

It was already lapped

Thanks fr the extra bit of advice. I'm just going to suicide it. 72*C is well within spec. The irritating thing is that with 1.5v I can get 3.5ghz stable, it just becomes a room heater. I can fit one more fan in, and will get that installed.

What version, only one version (0.96 IIRC) is correct. If its the latest version you must add 15*C to the temps reported as it incorrectly reads TjMax as 85*C when it is 100*C.

Here is my OCCT graph, highest it reaches is 72*C after 1 hour.
