what is acceptable temps?

[bryanW1995]

ok, I just couldn't resist the lure of a stable 4.2, so I'm going to keep it for a while. however, temps are a bit high and vcore is a steady 1.376. I run seti 24/7 so it will be loaded all the time, only break will be when I'm gaming. ran linx for 300 minutes with no failures and seti overnight a couple nights ago before I got scared of the temps. I'm using an antec 900 with the two front 120mm fans, rear 120mm, and top 200mm fans all on high, plus another 120mm fan that I had lying around on high on the TRUE. just cleaned out case. I don't have anything to measure it, but suffice to say that airflow is no issue at all. HT is on, that was my main reason for wanting an i7 over a thuban so I will drop down the OC before turning it off.

using real temp with tjmax set to 100, avg temps are 76, 80, 75, and 79 with max of 82, 85, 82, 87.

are these temps unsafe? and by "unsafe" I don't mean will it last 10 years like this, but more like "Can I run it like this for 18 mos until something better comes along then drop it down to 3.8 or so and put it out to pasture in mom's office"?

I would be slightly worried about the heat in conjunction with voltage. If you don't mind the raw look, try pulling a side panel off. It dropped my 920s temps about 10*C on a p182 with basically perfect cable management.

The average temps seem fine, its just that 87 that I don't like.

Is the CPU and the TRUE lapped? if not do that. It will probably drop your under load temps at least 3-5c or more depending on how flat the CPU/heatsink was to begin with.

My i7 930 for example was not flat at all, had a big depression in the middle and took me well over a hour to lap it to a mirror polished and perfectly flat 2000grit.

My under load temps with turbo and HT and all power saving/downclocking features enabled gets me to 77c core temps with 25c ambients.

With 35c ambients(no AC FTL) which is where i was at temp wise the week when i stress tested my OC would get me up to about 85-87c after 24 hours of prime. And turbo stayed on, and since intel states that turbo will only work when thermals are good and voltage is good im going to assume 87c is fine with intel, since it didnt kick it out of turbo.

Gaming it has yet to hit over 75c ever, even with the 35c ambients.

I would not run it at 87c all day long folding or whatever, thats going to greatly shorten the lifespan of the CPU.

That is HOT wow!

Nominal temps at load, what Intel says is , 50's to 60's celcius

thx

From most of the posts i have seen thats not going to happen with the stock cooler, a good aftermarket one will get you there if there is no overclocking. And overclocked is defiantly going to be higher than that, unless you have one kickass water setup.

that totally depends on what your definition of normal is.
Acceptable can be anywhere below fault temp, or thermal shut down temp.
Acceptable can also mean will only last exactly the warrenty period.
There is no real blue print temp max, unless were talking about thermal shutdown.

Link?

Yeah i would like to see one too.

Thats kinda mean..

Due to a faulty case fan i have run one of my computers i7-860 at 85 - 89ºC for more than 3 months without any problems or errors at all. The computer was doing distributed computing (seti@home, PrimeGrid and SIMAP) 24/7 and 100% load during all that time.
I have now fixed the case fan and the CPU runs at the same load 72 - 73ºC.

I do not know if the temps are safe or not, but I am surprised that not one WU was reported as invalid, and at least Primegrid is quite sensitive to errors in both interger calculations and floating point calculations.

That shouldnt surprise you because 89C is still within spec for almost all CPU's. It wont help longevity, but it should work error free at stock speeds at least.

FWIW I once owned a faulty A64. The PC would sometimes shut down when running heavy loads. I didnt even consider overheating as a cause since everything felt cool. The HSF wasnt even luke warm (and properly mounted); I even booted it once without heatsink and I could touch the heatspreader and not get burned.

Yet when I installed a temp monitor I found it would idle around 80C and loaded with prime it would quickly run up to and over 120C before the system shut down. I figured that just had to be a misreading. A faulty temp sensor. How could the core run at 100+C with my finger on the heatspreader? Until I realized the heatspreader didnt make contact with the die! Faulty chip. Removed the heatspreader and got a really cool and superoverclocking cpu

Anyway, my point; it never produced an error, not even at those insane temps.
