Controlling fan speed on HP IPM87-MP Memphis-S motherboard?

I have a bits-and-bobs machine that's been built out of a mix of whatever parts were at a price I was prepared to pay.

The motherboard is an IPM87-MP motherboard originally out of an HP Pavilion 500-386, and originally came with a Pentium G3240 installed.

However, it's apparent that the CPU fan speed is clearly not configured for the i7 I've replaced the original CPU with, and the fan never gets up to any real speed even when the CPU temperatures are rather hotter than I would like.

I'm not expecting great temperatures, as the current cooler is only the default HP one that came with the motherboard, but the poor fan speed is the main concern at the moment, because that would persist even if I replaced the entire cooler.

I have used SpeedFan on my previous machines to override fan speeds, but this time, while SpeedFan is reporting the fan speed, it seems to have no control over it.

So, that's the problem - what do I need to do to give SpeedFan control over the fan speed?

The main system specs are as follows, but feel free to ask if I've omitted anything important:
- Intel Core i7-4790
- HP IPM87-MP motherboard
- 2x 8GB DDR3-1333 RAM
- MSI GTX 1050 Ti 2GB Low Profile
- RM One chassis, Integral 19" Monitor
- Windows 8.1 Home 64-bit
- Samsung 850 EVO 250 GB SSD
- Seagate Barracuda Green 2 TB HDD

As best I know, the motherboard is updated to the latest BIOS and chipset drivers from the HP site (I haven't exhaustively checked every version number, but I was fairly thorough when I built the machine, and no new drivers have come out since).

Do try and check once more if any other bios update is available or not for the particular motherboard. Bios update should be done in an orderly fashion though, like if you have version 1 and version 2,3,4 is available, then download each version and flash it in an orderly fashion using the bios.
And also whats the temps you are getting? I suspect its a problem with the mobo cpu fan header. Also if you have any other fan connected like any chasis fan, check to see if you can control the speed of that fan or not.
First of all, pls do get a custom cooler like a cooler master hyper 212 evo or even a cheaper model will do but do get one for an i7... Next it seems the problem is related to your motherboard... Reset the cmos by taking out the battery of the motherboard, wait 1 minute and then insert it back in... See if it solves the issue... If it doesn't, then you need to change the mobo...
 

A Hyper 212 (or anything broadly similar) isn't an option, as it's a compact case (hence the low profile graphics card).

Yeah, I know - it's a lot of CPU for a small case, but I have run CPUs with similar and higher TDPs in this exact case before within acceptable temperatures. (Not great temperatures, but acceptable). I am looking for a suitable replacement for the cooler, but like I say, no cooler is going to be much good if the fans aren't getting up to speed.

I'll try a CMOS reset, although I'm doubtful. I've a feeling that any solution is going to override HP's configuration rather than just reset it*.

* Although I guess I am surprised that the configuration doesn't recognise what to do with higher TDP CPUs. While this specific motherboard came from a Pavilion 500-386, the HP Pavilion 500-330d is the exact same motherboard and was sold with the i7 4790 from stock, so a motherboard with the latest BIOS and drivers shouldn't just assume it's running a low power CPU.

 

Ohh sry, i terribly apologise, i didnt see the case or check out the model, you can try cryorig or noctua air coolers NH-C14 particular to mini itx builds. Now coming to TDP's , every motherboard can handle the tdp's required from that generation of cpu's. You didnt mention your psu. May i know what it is?
 

I have to admit that I left it off the list because I can't remember the make or model, and can't easily check - it's under a mounting bracket where some of the screws can only be removed by extracting the disk drives first. (Space efficient, yes. Convenient, no).

I know it's nominally a 450W supply, but if you need more specifics, I'd probably have to check with the friend I originally traded it from.

Anyway, I've tried popping the CMOS battery (to the point that it asked me to confirm some settings when I restarted), but it's not given SpeedFan any more control over the fans. It's still seeing them, but they're not responding to any overrides.
 
I do need to know the make and model of the psu... Any other responder here would ask you the psu details as it is a vital information towards proceeding to a resolution... Sometimes the psu cant provide enough for the system to perform to its maximum potential and this causes problems like black screen and freezes like you mentioned...
Edit: If you are unable to find out the details of the psu or if it is a unknown brand... its time to upgrade to a well known branded psu... A psu that would fit your case is:
Silverstone - Strider Gold 450W 80+ Gold... https://pcpartpicker.com/product/tfw323/silverstone-power-supply-st45sfg
 
Silverstone
... That's the name I couldn't remember! I've checked, and it's a Silverstone ST45SF.
It's not quite the model you suggested, but the mounting brackets in this case would actually foul the ports on a modular one.

I haven't mentioned anything like that though. Right now, the only problem I have with how the computer is actually behaving is that I cannot use SpeedFan to take control of my fans (or somehow otherwise adjust the fan speed profile).

Other than that, everything is working perfectly. I can run stress tests, game, browse the internet, process videos and the machine performs fabulously, it's just getting hotter than I want, because the fan's speed profile assumes a cooler processor.

Individual applications crash occasionally, because that's what applications do from time to time, but the machine as a whole is almost flawlessly stable under any load.
 
Actually, i was replying to a lot of questions on the forum and happened to mix things up. The previous answer was intended to a different question on the forum who had issues with his build and he was also using a mini itx build. I mistakenly post it here.
