M17X r4 - gpu upgrade Quadro RTX 5000

[Ollie87]

Good morning all,

 

System Spec

• Unlocked bios A12
• CPU - 3940xm - OC level 3 (padded using 11.4cfm fan with liquid metal)
• PSU - 330w
• current gpu - Quadro RTX 3000 6GB (previously 980M)
• Ram - 32 gig corsair Vengeance
• running on SG mode
• standard 60hz screen (i have a 165hz 2k panel waiting to install when i am brave 40 pin connector)

 

Ok, i have decided to upgrade the laptops GPU one final time, i have installed a DELL version RTX 5000 16 gb that i picked up, installation seemed to go fine. i had to take off a slight bit of the heat sink end to allow fitting to the card, the card shows in bios and in device manager, the issue stars with heat, i am running a alienware m17 x r4 gpu heat sink that is 3 pipe, i am using artic mx4 thermal paste, the temps slowly rise to 100c , ive tried running the fans at full speed and it does not make any difference to heat dissapation.

 

currently unsure if the drivers are causing the issue or the heat sink is no good for the card, very much at my witts end on this one, is there anyone out there who knows more than i do, i did consider undervolting the card itself, but as im unsure why the cooler is not working to cool, i also have a KLIM pad cooler with 4 x fans.

 

on the first time i switched off the system and rechecked the thermal paste the card felt very hot but the heat sink end did not feel as though it was transferring the heat along the pipes ?

 

has anyone else had a similar issue. any help would be much appreciated.

Ok after a strip down I've noticed 2 chips/ resistors that are sitting proud and in wondering if these are causing very low heat transfer to the heatsink itself ? I will look to Dremel the heatsink to slot these in better

No good, still have heat rising up to the 100c mark, I will proceed to try and undervolt the card.

 

I have realised I have made an error, heat sink was cut, I have just ordered a replacement, I did not realised these contained liquid, I will look to the chassis to allow an uncut sink 😔 that can be the only cause of the heat not transferring I assumed they were solid copper.

Very nice upgrade.

 

I believe MX-4 is an outdated thermal paste. I have an RTX3000 and with MX-4 and PK-3 temps were a problem. I switched to PTM 7950. Now the gpu tops at 75 degress with the hotspot getting to 84. 

 

I have an AW 17 so it uses the stock fun curve.

If its not the heatsink itself you might look at the pipes!

Just for reference....

thanks for the video, i never realized the pipes contained liquid, stupidly i cut the ends off to fit it into the chassis 😅, im waiting on a replacement i will need to look at this better, the heatsink on the card hangs over slightly by about 10 - 15mm from memory

Ok, so I have fitted the new replacement heatsink and it is keeping it cool, I need to work out a way to fix down the heatsink without butchering my case as the x spreader is off slightly
