Asus M50VM - High Temps, Fan Stays on Low Speed

I've been all over the internet looking for a solution and I really need some help.

I've got an M50Vm that at times does not cool down.

I get the NB Probe "fatal" warning; Speccy shows high temps for both CPU and GPU.

The problem seems to be that the cooling fan does not always kick in like it should. Whether it does or not is a mostly random event.

Speed fan does not work for adjusting the fan settings.

The fan itself and heatsink is more or less entirely clean of dust.

When the fan does kick in it usually makes an annoying sound and the sound will change from one kind of annoying sound to another.

I've never updated the Bios is the 2.5 years I've had the machine.

When plugged in I run it on P4G High Performance setting. I don't have the P4GHybrid nor have I updated P4G.

I don't know what else I can type now but I will share any info I can.

I really need to get this fixed and welcome your thoughts...

 

Is your fan making a grinding or rattling noise?

 

Yes it could be described just like that.

 

Time for a new fan.

You can try removing the fan and putting a drop of 3-in-1 oil on it. There's a nice pic here: http://forum.notebookreview.com/asu...ot-problems-fan-what-do-i-do.html#post7191609

If you're not under warranty, which is likely at this point, you will probably need to open it and confirm the part number. Then you can take to the internet and try to find a replacement.

It may be the same fan as the G50 series, you can read about some experiences here: http://forum.notebookreview.com/asus-gaming-notebook-forum/549408-asus-g50vt-x1-fan-problem-2.html

 

Thanks for all the info AllurG.

I was hoping to avoid fan replacement mostly because I have to remove the 2 long copper pipes as well (its all connected to the fan assembly in the M50V) and I'm a little worried about that as I've never done it before. Will need to get some thermal paste and go for it.

 

I'm not sure if this is the case wih the M50V, but with my W7sg, when you remove the 2 long copper pipes, you flip it over and you will see 3 screws holding the fan in, all you do is unscrew them and pop in the fan. and you should be fine -- i recently cleaned out my fan and it was a lot easier than i thought

 

hey Pear thanks and yes it sounds like the same setup.

Can you give any advice or post some links that help with the process, give some more detail?

In particular, when you unscrewed the pipe clamps (there are 3 locations for the CPU, GPU and something else(?)) will the pipes lift off those items without having to remove those items from the motherboard?

Was removing the factory thermal paste an issue? How did that go for you?

Any hints or trick to pulling the fan power supply cord from the motherboard?

I think doing the fan replacement should be the easiest step in all this.

Not having removed the copper pipes I'm not sure what I'll encounter and just want to be as prepared as possible.

 

btw there was this relevant addition to the m50vm disassembly guide here in the forum:

I guess if you check that disassemble guide, in the 2nd picture you will see the 2 pipes and the numerous "feet" that are sprawling out from the plates. You'll notice there are holes at the end of these -- all you need to do is unscrew the screws for those and flip it over and you'll get to where the 2nd picture is. For my W7sg there was also a power cable that powers the fan that might be in the way -- you an detach it or leave it in.

In either case when you flip over the 2 copper pipes / plate combination you, it will look like that 2nd picture. From there you'll notice 3 screws holding the fan into the copper/frame/fan-enclosure just take those 3 out and clean out hte dust (makes a huge difference!) or swap out the replacement part
