Laptop fan control software

IN B4 SPEEDFAN

With that out of the way, let's get to my problem:

I have a Dell Precision M4300. The motherboard is the same as the one found on a D830.
I have overclocked my GPU by +67%, and while my computer can handle the heat load, it doesn't know how to. It can rapidly bring down the temperature from 69Ccore, 80C GPU to a relatively cool 59C core, 67C GPU within a minute of the fans blowing at 100% speed (4500RPM).

The problem is, until a potentially dangerous temperature is reached, the fans turn around at a merry 2800RPM, barely more than the minimal 2300RPM. This late response leads to high temperatures, which leads to a thermal throttling taking effect, which means the end of a gaming session despite having perfectly capable cooling facilities.

My objective is two fold: Get the fans working earlier, give the fan a ceiling of 85% speed.

Yes, I have tried Speedfan and all of its options. I have ticked the dell support box. I have changed the Pmw1 to maximal 85%, minimal 50%. I created a fan profile that gets the fans turning at 3800RPM once the GPU temp hits 72C. I have changed the desired and alarm temperatures of every single component I have. And yes, automatic fan control is on.

All works perfectly fine until I stop plying.

They won't go back down.
I close the game client, temperatures fall to 51C GPU, 47C CPU but the fans still turn at 3800RPM. I try deselecting automatic fan control and turning down the fan speed manually...the moment I hit 50% the fans go to their lowest 2300RPM state for 10 seconds then start blowing at 4500RPM.

This is ridiculous. Why the hell would speedfan try and cool my computer past 45C core?! All my settings are asking it not to.

Putting automatic fan control back on is akin to just asking the fan to set itself on fire. The fan tuns at 4500RPM nonstop until I uninstall speedfan. Yes, this is the same automatic control that worked perfectly fine moments earlier.

Short version: Is there a speedfan alternative that works better with Dell motherboards? Or at least specifically for the D830 motherboard?

Thank you!

Notebook hardware controll will do the job

Only the paying version can change the fan settings.


My problems have been fixed after I discovered that the ik8fanGUI tool can set the maximal and minimal RPMs.....if the motherboard is supported of course redface.gif

My 'fan sensor chip' is not supported. Checking the list of supported motherboards, I find the D820 is supported. According to Dell, the D820 and the D830 have the same fan...so here's my last question:

Is there a way to trick ik8fanGUI into thinking I have a D820 motherboard?

The roof just crashed onto my head.
Okay, that aside, can't I like, force the ik8fanGUI utility to send instructions as if it were on a D820 motherboard. There must some file in that program that gives it different instructions for each motherboard detected, can't I just make it execute the D820 one?

PS: You're telling me the alternative is to wake the utility maker from the dead (Christian Diefer) after he dissapeared from the internet some time back in 2011...

Problem fixed by using Asus GPU tweak's laptop fan profile. It works now, for some reason...
