No. Yes. No.

Google will help:

https://www.google.com/search?q=recommended+gpu+temp

1) Is fan spinning?
2) Is heatsink fins clogged? Pet fur can create a great 'felt' pad under
fan.
3) Is there any other obstruction in air flow within box?

Take care,

My AMD A10 APU came with a monitor program, and one of the options is
reading the sensors, voltages, and fan speeds.

Just a word of warning: with any of these programs, if the temp displayed
looks totally outragious in either direction, it is probably bogus. Not
all
motherboards and/or cpus implement temperature sensors in the standard
way.
If you didn't get a monitor program with your CPU (check the vendor
support
page, it may be there) try several of the listed programs in the following
posts and take the consensus. Once you find one that seems to be accurate,
stick with it.


Thank you everyone. I'm trying "Core Temp 1.13"
for a while.


Of all the ones listed, I like Core Temp the best. I don't know if it's the
MB or CPU sensors, but my Athlon X4 845 (and a previous AMD CPU) has always
shown it idling at 0C. Now, I know that can't be right :-( Core Temp allows
an offset to be put in to adjust for temp correction. A number of articles
say this CPU idles at ~26C, so I put that in as an offset and everything
appears to be normal, or at least closer to what I'd expect.

I have overheat protection set in UEFI and in Core Temp, and have yet to
have it shut down, so I have to assume the offset is at least close to
correct :-)


I have all the items required for water cooling,
but it's not set up yet. Should I bother if I'm
not a gamer?

You fix it.

You fix it for *two* reasons.

1) When it rests at Tmax like that, it's throttling.
That means, it inserts a "No Operation" or NOP into
the instruction stream at regular intervals, to cool
off the CPU. This causes the time to convert your
movie to increase (not good).

2) The materials the CPU package are made of, are at
their temperature limit. The silicon could likely
be heated to 135C. The 99C limit (enforced by the CPU)
is related to the organic packaging. At one time,
CPUs came in ceramic packages, and the packaging was
less of an issue, and the silicon simulation temperature
and max die temp were the limits back then. Today, the
"package is the first thing to go".

If this is a laptop, you clean the fins on the CPU heatsink
(that the blower blows through). In addition, you verify the
fan rotates freely, without ruining the bearing by pressing
on it too hard. Don't jam a kitchen paring knife into
the bearing to clean the fan. It's delicate. (I ruined
a fan and that's how I know :-/ )

On a desktop, you have the option of "re-engineering"
the cooling. You can replace the thermal paste.
You can use a cooler with heatpipes and extra large
fin array. For example, my CPU runs at 43C when running
Prime95, and the cooler is so big, it has a "support leg"
to hold it up :-) When I encode a movie, nobody gets
in my road.

In addition, on a desktop, you have the option of buying
a new video card. The new card has "NVenc" block in the
video card, and can convert H.264 to H.265. If the video
card does the conversion, it runs 10x faster, and the CPU
just "sits there and watches in disbelief". The video card
only gets moderately warm (as only the video block is running),
and the CPU is back to room temperature or so, because it's almost
idle while the movie is converted. NVidia has NVenc and
AMD has VCE. If you have a copy of Handbrake, I think there's
a status screen that shows whether the subsystem has the
correct driver installed and is ready to go.

Video card encoding isn't always the best quality
(single pass), but the sample I looked at, looked damn
good. It almost looked like the conversion had applied
a tiny bit of sharpening or something.

No matter what your CPU is intended for, there's no excuse
for it sitting at 99C. Someone didn't do their job right
if that happened (too small cooler, blocked airflow etc).

IMO it's bad. Not too bad, in that it will continue to run at that
temperature (obviously), but that temp will degrade it faster, so rather
sooner than later the CPU will fail. FWIW, the CPU on this box is
running at 55-56C.



I have no pretenses on being an expert on this, but 55-56C sounds
pretty hot to me. Mine is around 34C here.

You need to load up the CPU for a decent test.

Having a CPU idling at 55C, means when you use it for
something, the temperature is going to shoot higher, and
it might end up throttling.

CPUs with small silicon dies are harder to cool than larger
silicon dies. The Athlon with the bare die was reasonably
small. And harder to cool when you lowered a heatsink onto it.
Even though at the time, it was a 65W CPU.

A "good temperature for an Athlon" was 65C under load.
They seemed to be happy there. On boards with the
THERMTRIP addon chip (Attansic brand?), the power would get cut at
85-90C perhaps.

*******

There's a claim that "LINPACK" heats up a CPU better
than Prime95, so I tested that out.

There is a tool here that uses a LINPACK executable.
As an example.

https://www.techspot.com/downloads/4...lburntest.html

https://files01.tchspt.com/temp/IntelBurnTest.zip

( https://www.raymond.cc/blog/test-sys...tem-resources/ )

But what I tried instead, is just getting a LINPACK from
the Intel site.

https://software.intel.com/en-us/art...nchmarks-suite

Windows* package (w_mklb_p_2018.3.011) (.zip)

w_mklb_p_2018.3.011.zip 7,536,943 bytes

Using 7ZIP, look for the "linpack" folder.

w_mklb_p_2018.2.010\benchmarks_2018\windows\mkl\be nchmarks\
linpack
runme_xeon64.bat

In a compiler directory are a couple DLLs and a PDB (symbol table).

w_mklb_p_2018.2.010\benchmarks_2018\windows\redist \intel64_win\compiler\
libiomp5md.dll 1652992 bytes
libiompstubs5md.dll 110848 bytes

Add the DLL kit into the linpack folder, then

Command Prompt (as regular user)

cd /d %userprofile%\Downloads\linpack
runme_xeon64.bat

Then, watch your Speedfan chart for temperature results.

*******

I ran Prime95 as well, just whatever copy I had
handy, and it's sorta in the same ballpark. The
latest is here. At some point, the author of this
tried perhaps, to use AVX512 or similar and some
bug was uncovered. I don't remember the details,
and perhaps the program is back to the old way of
doing it. AVX512 heats up processors enough, to
have its own protection/prevention scheme (the
very definition of useless).

https://www.mersenne.org/download/

Windows: 64-bit 29.4b8 2018-02-09 6.1MB p95v294b8.win64.zip

The advantage of that one, is "double-click to start" on the
EXE, and only answer one prompt ("Join GIMPS" - answer "Only testing").
After that, accepting the defaults starts N threads of test
and makes your CPU heat up. Select Exit from the menu to stop it,
as it'll run in the tray if you iconify it.

These are the charts from my runs. The Intel Coretemps
are used for the charts, and those have relatively large
error bars at low temperature. That's how cores can end up
reading "sub-ambient" temperatures.

The delta on the two tests is about the same.

https://i.postimg.cc/HnxGsc6m/linpack2.gif

https://i.postimg.cc/KcqSpfY8/prime95.gif

One run was drawing 208W, the other 211W, on my
Kill-O-Watt. The power before the test starts
is 95W or so. (Power varies on the machine, according
to whether hard drives or used - in this case, the
SSD boot drive gives the 95W power figure.)

The machine goes higher, with a little help from
the video card.

I would say if it's a PITA to do it, and your current temps are acceptable,
why bother?
If I had the complete kit, I might give it a try just to see what it does,
but probably not- I'm just not the "try it and see" guy any more; I have
better things to do :-) (Well, in my mind, they are better things to do,
LOL!)

I have just rebuild and used a Corsair H80i vs All in one water cooling
system.
I changed to a case with better airflow..and replaced a Noctua NH-D15 Air
Cooler.
Running a 30% overclock on an Intel I5-6600k . My "normal " temps went up by
1 degree..
When I run prime 95 or RealBench or IntelBurn which stresses the CPU and in
the case of RealBench the GPU as well
my temps are the same as they were with the Noctua air cooler...Under stress
I reach 55 C..
The H80i has 2 120mm fans running in push/pull config....its by no means the
best water cooler but i bought it to
see how it would do.If I were to repurchase I would by a larger
one...240mm.... The Noctua ran fairly quiet and so does the
H80i until the heat cranks up the fan/pump speed.
Hope this helps in your decision making

Too hot to touch starts at about 60C.

99C Is this good? bad? or indifferent?

IMO it's bad. Not too bad, in that it will continue to run at that
temperature (obviously), but that temp will degrade it faster, so rather
sooner than later the CPU will fail. FWIW, the CPU on this box is
running at 55-56C.

Best,


Thanks everyone who tried to help...

Turns out the thermal paste had given up and needed replacing... So I
did that.. Then I broke the pin holding the sink to the motherboard so
That's getting fixed
I use SETI to run the CPU hot.. seems to work well at that

More as I know more

Thanks for the feedback heads up. :-)

Thermal paste giving up? Never thought that could happen, will have to
open this box and do a thorough inspection and clean. Haven't opened it
in 5 years, and CPU temp is in the 50 to 60C range, on the high side of
acceptable.

Best,


Generally, you take note of the temperature performance about
three days after installation ("bedding in time"), then
check over the years. If the temps under the same conditions
have risen by 10C, you might re-apply the paste.

Thermal pastes with particulate in them, tend to "settle" a
bit after installation. Whether they have silver particles
or boron nitride ("ceramic").

The only time you'll be in real trouble, is when the
clamp on your cooler, snaps off the tab holding it down,
and the cooler is "just hanging there". Throttling and
THERMTRIP on modern systems, protect in that case. It's
on systems that have no thermal monitoring whatsoever, that
CPUs get fried (Athlon before AthlonXP).

On the Intel systems with the push pins, sometimes one of
those will come loose. Especially after the push pin has
been "cycled" a number of times and it no longer fits right.
The push pins involve a 90 degree rotation, between
locked and unlocked. Plus they use a "spreading" notion,
that makes the plastic bit behind the motherboard, too
thick to fit through the mobo hole. Intel has some
install videos, if you want to see how to operate
their fasteners properly. The Intel cooler is perfectly
good... on their lower TDP products (65W CPU that only
draws 36 watts max).

*******

One way for thermal pastes to fail, is by migration.
Zinc Oxide in silicone oil is fairly motile. Some
other preparations are specifically constructed to prevent
that. The Intel "screened" material which is "hard" and
"melts" when heated, then cools and solidifies afterwards,
that stuff usually stays put. If you need to change that
out (the stuff is "too rough" for the CPU to seat again),
then the material has to be scrupulously removed, with
some chance of damage to the metal underneath. I mention
that, just so you have some idea of what you're headed for :-(
I've cleaned one of those off before, and it wasn't all
that much fun.

Some new pastes have a "crumble" consistency and don't
"spread" like butter on a cracker. If I read a description
that a product is "too thick to spread" and "crumbles", I
just don't buy it. I'd sooner have a toothpaste-like
consistency and have to change it every five years, than
have a miserable-to-work-with material.

If you want "novelty materials" there is gallium liquid metal.
