MSI GT70 0NE-452US Fan issue.

I have bought a MSI GT70 0NE-452US which i had enjoyed for a while, until i have observed very high temps while gaming (90+) even with the fan throttle button on. After removing my 680M and reinserting it with fresh paste it never worked again. So, i have removed the nvidia drivers and now i am using the on board card (intel 4000).

My issue is that if i completely remove the 680M module and turn the laptop on the fan throttles to maximum, after around 1 minute. If i leave the faulty 680M on, the fan does not throttle but i experience delays in booting and sometimes the laptop turns on and off several times before booting fully.

What i want to do is remove the faulty 680M so that i can use my laptop with the on board card and solve the fan auto throttling after around 1 minute. My guess is that the fan has a sensor to detect the 680M and throttles when the card itself is absent but i would have assumed that the laptop should work fine without it.

In fewer words: Can the laptop boot normally without requiring an MXM card installed?

I would appreciate any information on this issue.

 

has anyone experienced anything similar?

 

Hoping for a response

 

Hey athosprv

I don't have anything definitive for you, but spitballing, I'd say this has something to do with the Optimus. Since you can't disable switchable graphics in BIOS, I don't know that there's a way around this.

Does your system continue to boot as normal without the 680M installed? Despite the fan revving.

 

Thanks for the response

Without the 680M the system boots normally and very quickly as well. The fan none the less, does throttle after around a minute (regardless of being in the bios or in the OS)

I thought about buying a cheaper compatible GPU to make it shut up but i really hope there is a bios update or maybe a fan replacement option to make it stop while using the onboard card.

 

Throttling is actually the opposite of it revving higher. But the terminology aside, I'm not even sure a modded BIOS would fix that, if there's one available.

 

Well when i mentioned that the fan throttles after a minute, i meant that it goes from normal to 100%(at full throttle, at maximum speed or effort.) instantaneously, similarly to pressing the fan button on the keyboard.

While i am considering any possible options, i will be searching for any similar cases to see what the best solution would be to the problem. As of now, i left the faulty GPU on and uninstalled the drivers to force the laptop to switch to the onboard card.

It works for now but i don't really want to leave faulty hardware on.

 

Sorry to hear you're in a rock and a hard place. Have you tried software to control the fan? Something along the lines of SpeedFan - though I'm not sure whether it supports that board or not.

Best of luck to you! If you can't find a workaround, hopefully you can find a new card without breaking the bank.

 

Thanks for that tip. I will be testing speedfan to see if it will work

 

What you've experienced regarding the fan spinning at 100% is normal if you pulled the GtX680M. Me and forum member ryzeki both tested and experienced the same thing. I think it has sometime to do with the BIOS or the sensor.

The laptop will work normally without GTX680M installed:

Thanks for the response and link.

Its great to see that there is nothing else wrong with my laptop. At this point all i want to do is remove the GTX680M and leave the laptop with the onboard card but i definitely do not want to hear the loud noise.

Have you tested any software to see if they can tune it down, such as SpeedFan?

 

I tried speedfan but it doesn't work.

 

Thanks for trying

 

keeping this alive in hopes that someone has found a solution to the issue

 

I have the feeling the only solution will be more of a workaround, as the fan revving seems inherent when it doesn't detect the card. It will probably involve some sort of mod.

 

You'd want to flash the unlocked bios and select integrated only mode.

 

I don't have an MSI, but a Maingear Nomad 17, that uses the same chasis and AFAIK the same BIOS. Where I can find this "unlocked bios" to disable Optimus?

 

you can find the unlock BIOS here, Xonar is also a NBR member:

MSI G-Series Unlocked BIOS

 

Do remember to get a backup of your existing bios in case you run into issues.

 

Im really sorry to Necro this. I have recently done a Bios unlock and i am trying to find which option would disable the fan going to 100% speed.

Has anyone come to the bottom of this?

 

You want to change the default graphics to IGP.

 

Thanks for the response. Before i had checked the forum i changed the default graphics to PIC (stupid mistake) and now the laptop wont go past the MSI Loading screen. Is there a guide i can follow to reset BIOS?

 

Yes, remove the AC and battery, then unplug the little cable that attaches next to the CPU heatsink (2 pin red and black) this connects the cmos battery to the motherboard.

Leave that for a few minutes and/or short the 2 pins on the motherboard together and place everything back in.
