Re: Medion mim2300 fan mod

What happens if I only cut the white/yellow cable?

Re: Medion mim2300 fan mod

why going directly to fan? fan is drived by mosfet, so inject voltage to its gate. 5V is way high sound for normal work. i preffer 3,3V.

A bit old but then again I'll refer to the sentence if the customer doesn't mind it its ok .
Yet the laptop failed (reball didn't help but a new GPU did ^^).

Yup. It's not the soldering that's defective on those GPUs, it's the GPU itself. A re-ball is a temporary solution at best.

Re: Medion mim2300 fan mod

Thx for reply. I think my old notebook isn't worth the money for a new gpu. I also don't have the equipment to change this onboard GPU. Thats THE reason why I'm searching the easiest and cheapest way to fix it for a time. So, does it work if I only cut of the white/yellow cable to speed up the fan?

Re: Medion mim2300 fan mod

why cut anything? just inject 3.3V to base of fan driving mosfet.

Re: Medion mim2300 fan mod

Sorry but I'm a newbie. I don't know how to inject 3.3v to base of fan driving mosfet. That's the reason why I'm asking for a simple solution or pics how to do it.

Re: Medion mim2300 fan mod

its easy method. fan connector is connected to 3-8pin ic. one of its leg/gate/ just wire to the big coil of 3.3V rail

Re: Medion mim2300 fan mod

Well I needed 100% (or more fan speed) to keep the GPU's temp down (just to prolong its life till the new one didn't arrived).
Its a messy solution gotta agree on that, but in the end a new GPU with normal cooling (without any soldering) solved the case.
Your solution applies more to a normal working laptop for which you want better temps (not to keep it alive xD).
