How to turn down fan speeds without a video card?

Haylex · Feb 14, 2015

So a few weeks ago, my NVIDIA video card was damaged. It had to be taken out for my computer to turn on, or replaced, and because I didn't want to spend the money replacing it, I opted to just use my integrated graphics card in my laptop.

However, now the fans in my laptop are running at full speed all the time, regardless of CPU/GPU temperature. I've searched over several forums for a solution, and I've looked into several different programs, including MSi Afterburner, NVIDIA GeForce Experience, SpeedFan, Riva Tuner, and RWEverything, but to no avail. Most of them require a video card in order to control the fan speeds, but since I don't have one in my computer, I can't change anything.

Laptop:
- MSi GT60 0NE
- (Had a) NVIDIA GeForce GTX 675M
- Integrated Graphics: Intel HD Graphics 4000
- Running Windows 8

Any help would be appreciated, and I can provide more info if needed! Thanks!

To be honest, most of the other fans in the laptop are controlled by the bios of the laptop.
It`s only a graphics card that comes with control software you can use in windows to control the fan speed and for overclocking. Afterburner ect.

If you look in the bios of the laptop, considering it`s a gaming laptop.
You should have a bios that is fully featured in options unlike cheaper more basic laptops with limited bios options and menus.

In the power section or, health section there should be an option to control the Fan that cools the cpu.
It will be based on the rpm speed of the fan depending on how hot the cpu is in the system.
You can set the power curve percentage in rpm based on the Cpu heat in F or 0c in this section.

Oh yeah, I looked in the bios as well, and there's no option for fan speed or anything. Honestly, the bios in this laptop is actually LESS featured than in one of my older, non-gaming laptops. It's got boot settings and SATA settings and some security settings, and that's pretty much it.

It's BIOS Version E16F3IMS.50T, if that helps at all.

Well the laptop will have quiet and extensive cooling solution.
So it is likely you have two plates with a copper heat pipe on each, one for the cpu and the other dedicated to cooling the graphics card via a heat pipe.

That means the laptop will have two fans one for the cpu, and the other once again separate to cool the graphics card independent.

It is likely that since the card cannot be detected, or you removed it, that the bios can no longer read the the therm o diode of the Pci-e based card. by default it will spin at max rpm.
So the only way to make it quiet is to disconnect the fan from the header of the laptop motherboard. It`s the only thing I would look at doing other than buying a new card.

BTW what happened to the old card? did it start to display artifacts or colors on the screen while playing a game ect.

Yeah, that's what I was thinking, but I didn't want to just disconnect the fan, as my CPU might overheat. But I'll do some diving in and see if I can get something working.

Thanks again for the help!

Hey, so I disassembled the laptop to get a better view, and it looks like the fan that's causing the issue is cooling both the CPU and the GPU. There is a second, small fan on the other side of the laptop, but it looks like that's for the hard drive or something.

The old card short-circuited or something. It's got a burn mark across one of the circuits. Basically, while it was in my computer, I couldn't turn the computer on. Removing it was the only way to get the laptop to work again.

I see, well it`s considered as a Short circuit when something blows.
Most mobo`s are set to detect this as you can or have seen to prevent any more damage to the rest of the laptop or computer.

But I guess you knew that. ;-)
Sorry I could not think of another solution for you.

That's fine! I will continue looking into it. Thanks again!
