Changing automatic cooling by the motherboard.

Dannyg123 · Dec 30, 2016

I'm having a really weird issue with the way my motherboard cools my PC which is causing constant bluescreens meaning i basically can't use my PC under load. Every time my PC goes under load my PC does't accurately record the temperatures of my CPU. The only way I could find of fixing this issue was to get another motherboard with better drivers so the automatic cooling is more accurate.

I was however thinking if i could just stop the motherboard from trying to control the cooling of my PC. I know this might seem a dangerous as the PC may legitimately overheat and the PC wont respond but i'm able to control the temperatures more accurately in speedfan.

I was just wondering if this is even possible or a really stupid idea but i'm willing to try anything at this point because the next best thing is replacing the motherboard which id rather not do.

Thanks

You should be able to set all fans to max or just plug them into a fan controller of some sort. BIOS may get upset if it can't see a rpm above min. threshold

You can get a fan controller like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16811992012&cm_re=fan_controller-_-11-992-012-_-Product

...and manually control the speed of your fans, and just keep them at, say, 70% all the time. If your motherboard isn't accurately reporting component temps, then there's no software that's going to automatically control the fans any better for you.

I haven't used any fan controller software, but perhaps there's some software out there that will save you the expense of a hardware fan controller and allow you to just peg the fans at a constant RPM. After that, trial and error to find the best RPM that is a balance between what you can stand to listen to and what keeps your computer cool enough to never overheat.

You could just disable "smart fan" or whatever it is called on you motherboard, then set a good fan speed, if you don't have a super loud CPU cooler, I haven't played with speedfan enough to know if it's safe, or if you could do it. And oh, you might be able to create a custom fan curve.

Iv'e tried changing and disabling smart fan and tried increasing the speed of the heatsink fans but nothing is convincing it its cool enough.

Just for context heres a screenshot : https://gyazo.com/f6d524a0907bb37a6446cff8a640f33b

Temp 3 is what my motherboard registers the temperature as and the Core label is the actual temperature of the CPU. When the PC gets under load Temp 3 will rise well above 80 Celsius despite all the fans being on and the actual temperature of the CPU being at a healthy 35-40 under load.

Are you using SpeedFan ... if so, it isn't all that reliable ... works great with some boards, borks up others

Dannyg123 · Dec 30, 2016

I checked this on speed fan and on HWinfo both say the same thing

JackNaylorPE · Dec 30, 2016

SpeedFan is likely the source of the problem. Speedfan is a utility which peeps use when:

a) The MoBo manufacturers does not have a fan control utility
b) The Owner does not know that the manufacturers has a fan control utility

It is what is controlling the fan speed is it is present and it may or may not be properly configured for your MoBo. If your MoBo supported ?

My motherboard isn't on the list so im assuming it can take the measurements quite accurately. I also headed into the BIOS and looked at the temperatures, the temps i was able to record from the bios aligned quite closely to the speedfan ones.

JackNaylorPE · Dec 30, 2016

I don't understand that conclusion. The opposite is true:

Here you can find a listing of motherboards that users like you reported as being able to change fan speeds. This is a subset of the hardware that SpeedFan can properly work with.

so if the MoBo is not on the list, you can reasonable assume that:

.... no users has reported SpeedFan as being able to change fan speeds. More likely than not, you have hardware that SpeedFan can not properly work with.

If i can't use speedfan in order to control the fan speeds properly is there any software which i can? It clear that the motherboard isn't accuratly taking temperatures itself because it bluescreens when the components are at a healthy temperature. I don't know why my motherboard insists that the components are so hot and bluescreens, its probably a drivers mismash.

Yes, on your original MoBo CD (and on vendor web site) there is usually a utility suite which includes a Fan control utility. Since this became the norm, SpeedFan kinda faded into oblivion. This can also be addressed in your BIOS, but with less range and features.

Both are described in your MoBo manual. Would also suggest HWiNFO for all your identification and monitoring needs
