Soldering on a new fan connector

Hi all - 

 

Recently I just bought an old Tesla M40 with 24GB of VRAM to replace my Titan X Maxwell for Deeplearning. As it is a passively cooled server card, I bought an aftermarket Arctic Accelero IV cooler and installed it so the card wouldn't overheat. However, even though the Tesla is just basically a Titan X with more VRAM (same GM200 die) it doesn't have a fan connector on the PCB because it is meant to be cooled by external server fans. Thankfully Arctic thought of this and included a molex fan adapter with the cooler. But it runs at a static speed and the card still overheats.

 

I still have my Titan X fully assembled. Would it be possible to de-solder the fan connector from the Titan and re-solder it onto the Tesla so the GPU has control over the fan speeds? Or will the VBIOS not do anything because it isn't meant to have a fan in the first place? Suggestions are welcome.

If you are running the cooler fans at full 12v, then soldering a PWM fan header to your graphics card will not help. Soldering would be the easy part, I would be more worried about cards BIOS and it actually having a fan controller. I wouldnt bother at all.

The Tesla won't be able to make the fans go any faster than the 12V from the Molex. You're going to need to find a better cooler.

Make sure the fan 's airflow is funneled over the GPU, just like they do in servers. Because thats what it was designed for. ;)

 

When i ask for more specs, don't expect me to know the answer!

you have to make a fan controller yourself because teslas doesn't have one

if it was useful give it a like :) btw if your into linux pay a visit here  and i will be thankful if you send me an opinion here

I'd check your mounting pressure-- an Accelero IV should be able to handle that card without issues.

I just remounted it with a fresh application of Mx-5. Still shoots up to 90c and throttles itself to 300mhz clock. Fans r plugged into the 12v adapter.

 

Also weirdly says that VRAM is full even when idling. I’m using it purely for compute. I have an AMD 5450 plugged into the pcie 2.0 slot for display because the tesla has no video outs. Might be driver related?

You sure all the VRAM and chokes are also covered with some heat transfer material?

The card has no physical damage etc?

Card has absolutely no physical damage. In fact it and the Titan X are 98% identical in board layout. only for a few different resistors near the chokes. So if I can mount this on a Titan X, it should 100% mount fine on this Tesla.. all the VRAM and Chokes are covered with the included thermal pads.

Thread solved... had to remove washers from cooler in order to make sufficient contact, even though the use of washers are required in the manual.  Card only goes up to 60c now without washer attachment and felt more solid contact-wise. Weird.

Thank you very much for reporting back. :)
