Windows 10 Pro CPU temp monitor program

[GH85Carrera]

OK, I am returning to the Pelican brain trust once again.



I am using a program for my Aerial mapping business. My system was built with total overkill as my home Email and Quicken system. Now it is being pressed into duty for business. THe program will get to points in the process of using all 4 cores, and 8 threads. 100% of the memory, and then have to hammer on the hard drives.

I need to replace the spinning hard drives that are a 1TB mirrored RAID with SSD drives soon. That will be a pain but necessary. Now to the point.

Today I got a CPU over temperature warning. I can see the temps in the BIOS, what program do you recommend to monitor the temps of the CPU, memory and motherboard. I plan to add a bigger CPU fan and add another chassis fan to the 3 chassis fans on there now.

What is the good monitoring program that does not use a lot of resources?

A lot of the time the MB manufacturer will have those utilities available.

I have used Speedfan in the past but don't know how good it is on Win10. I know a couple case manufactures make them as well. NZXT (?) I think is one.

speed fan

gives you readouts of all loads of temp sensors your mobo factory probably didn't know it had in there.

and you can manually control your fans

The motherboard is several years old. It was build with Win 7 Pro. The CPU fan utility that came with it does not work on Win 10. I tried.

That program was real clunky when I played with it when the system was new. It wanted to cover up some of the screen at all times.

Cool. That works great. Downloaded and installed. Working great so far.

[flipper35]

Glad it still works with Win10.

The temp management must be at the BIOS level not at windows 10 level.. That is a bad idea..
Sure you get all the gages and other pretty stuff but it can die, get stuck, become unresponsive like any other app on Windows and pfft! You just fried your PC.

Since your computer is old try this:
1. with compressed air clean all the ribs in the processor and replace like for like fans..
2. Ensure the BIOS setup is set to automatic for Temp Control.
3. Add (if needed) another fan in the case, like side vents, etc..

If that fails. You are really going to hate that computer cause it will let you down at the worst possible time..

Maybe just get another one and newer.
New processors are more powerful and run cooler.. (they're a bit slower but have multiple cores)

good luck!

OK, as a followup that no one but me cares about......



This is the CPU cooler that the motherboard came with. Not a small fan, but not huge. The system was free of dust and crud. With the CPU running at 100% it would overheat within an hour and a half and just lockup. Only a hard reset would work.



The new fan is huge, and has a mount right to the motherboard that is a challenge to make it fit. I had to pull the motherboard up a few inches to get the back-plate of the mount to fit into position. The clip that holds the fan onto the CPU nice and tight is a complex mousetrap that has a lever that locks it into position. I needed a 6 your old boys hands to get in there but I have large hands so it was a real pain to me but I finally got it locked down. The case and motherboard I have made it tough. The motherboard has plastic channels that pump air to critical components and I had to modify the clamp gizmo just a little with my drill press and a bench grinder. It fits with very close tolerances.



With the big mambo mega cooler it is a cool daddy-o. That one errant wire that is on top of the little motherboard fan is one of the temp probes. It was zip tied back into position to monitor the RAM.



You can see the fan through the vent holes and I can add one more fan to the case if necessary.

With the stock fan the CPU would run at 65C and finally just give up. Now it never gets above 40C even after 12 hours of running at 100% on all 4 cores and 4 threads. The RAM is running all 32 GIG and the hard drives are hammering away.

I use this computer mostly for the smaller jobs. We have a 12 core CPU machine with 128 gig of RAM and all SSD drives for the biger projects.

Next step is change to all SSD drives on this machine. It has 3 TB and two 1TB drives now.

nice setup but is that new fan pushing or pulling air? (you want to pull not push) and if it's pulling then the hot air is going the wrong way into the case.
Also that side fan (that intersects with the new cooler) that should be disabled cause its right in the middle and will distort the flow..

Anyway don't mind me.. you have it working and its 'cool', just thinking out loud.

The CPU fan is plowing toward the rear fan. The top fan is blowing out and the rear fan is blowing out of the case. A fan low down in the front pulls in cool air.

[John Rogers]

Do you have any dogs and/or cats? The front fan down low is a prime candidate to suck in hair. I moved my front fan to the top of the case for this reason, still get some but not as much as before.

[svandamme]

You need to establish a positive airflow and prevent turbulence inside the case
That means more fans blowing IN, then fans sucking out.
Sucking it vacuum means less dense air = less cooling.





Suck in cold at the front, blow out hot in the back

Avoid sucking in or blowing out at the sides as all that does is mix up your cold intake with hout exhaust

So loose that sideways or top fan that sucks air from the intake and exhaust of the cpu fan

Use baffles to prevent turbulence from the cpu fan, and make sure sucks cool air right from an intake case fan, and blows out straight to a case exhaust fan.

And seal off case holes and vents that are in the wrong location ..

Can't tell exactly how the case looks like, but most cases will allow all of the above tricks. the mistake is really trying to use all case fan locations instead of picking them strategically and closing off the ones that aren't used

I have this

Fractal's double-wide Node 804 case can swallow a dozen drives - The Tech Report



4 120mm Fans sucking air in at the front
1 120mm on the mobo side blowing out at the back
1 140mm on the disk side blowing out at the back

top, sides and bottom is all sealed up

It runs cool as a cucumber and is near silent

[svandamme]

oh btw, the speedfan temp readings, you need to correct those.
Some will be off by XX degrees

check their value on powerup when the board is room temperature
Any temp prope listing high values : adjust the difference so the probe is corrected to be same as the others. at room temp

[GH85Carrera]

If was interesting to see the speedfan temp reading and RPM readings. The CPU fan over doubled in speed from "idle" speeds.

On my system there is a12 inch fan down low in the front. There is one fan on the back up high blowing out, and the fan on the top at the back blowing out. The vents in the photo are right over the CPU fan and the CPU fan blows towards the back and the read fan just helps is go.

The system has been on all day and the the CPU is at 33C. The fans are running at 60% of max. It is working great now. That giant heat sink with a fan of the new CPU cooler is doing great.

It only warms up when the system is working at max.
