My fans on my 7560 are rattling badly. I clean them semi-regularly (~3-4 months), and replace the paste, but this rattle is very new. Oddly enough, it goes away when the fan RPM goes up. 

I may need a new heatsink assembly.

 

I'm still using the 7560 at work.

 

I also started to have rattling fans at certain RPMs. Fortunately, I was just before the three-year warranty cutoff when it started so I just had them ship a new heatsink out. That did take care of it.

Sadly my warranty expired last August, so I'll have to buy it out of warranty—need to see if Dell UK (yes, I moved to the UK...) have a number I can call. 

 

The notebook as a whole is a tank, and I fully expect it to last until 2030, or at least when this Middle-East/AI component supply crunch is resolved and prices become a bit less mental so I can build my nice home workstation/gaming rig, relegate this laptop to a family member, and buy a Surface Laptop for on-the-go use.

Quick update: bought a new heatsink assembly, installed it, fans even whilst running are nearly silent. I forgot how quiet this laptop used to be.

I do have to remember to clean mine every few months in order to get the fans back to "silent mode" again ...

Funnily enough I think what made my fans rattle so much was my rather overzealous cleaning, because I removed the fans from their magnetic mounts and brushed them every 4 months or so.

Oh, I don't take it that far, I just blow them with air from every angle that I can manage. (And mine still developed the rattling, too.)

I've browsed this thread for a while now, alot going on here lol. I got my precision over a year ago, and its been through hell and back. 

It came with the standard i7 and t1200. I upgraded it to an rtx a4000. I use ubuntu on it for battery life(with nvidia disabled) unless i am on a charger. I've tried ptm but didnt have great results. I recently put liquid metal on everything, and while the gpu under load doesnt get above 65, the cpu throttles hard(100c) even when undervolted by -75mv, on 330w charger. Dell power management tools dont exist in linux as far as i know. Is there anything else I should be doing in linux/hardware/paste wise to fix the high cpu temps?

EDIT:
I needed to replace my display today and found that the touchscreen/ir cable was between the heatsink and the vrm. after the display replacement, my temps(without changing lm out) is on load maxing 80 under full turbo/40c at idle(50-60 before) OOF

Hi again, I've been reading though these conversations to try to fix my issue. Whenever under load, the (RTX A5000) GPU throttles at 55W; it just stays at that limit, despite:

temperatures being in the 60s/70s for cpu and gpu 

computer always being plugged in and with a full battery. (played with different battery settings in BIOS, nothing)

This usually happens when under load, closing down the heavy program restores the limit to 115W/130W,

also the power limit will only show 130W when idle, under load it always goes to around 115-120W, is that normal?

 

Honestly, I have no idea when this start, I only recently decided to investigate this, which was why I updated my BIOS.

 

Most recent BIOS, 1.41.1 I think.

Adaptive C-states for Discrete Graphics is off

I played with different thermal settings from ultra performance to optimised.

 

I am on Arch Linux. I don't have a Windows drive to test, but I think that a Windows user also had a similar problem somewhere in these pages.

 

Updated driver/firmware, relatively lower temperatures, could it be possibly a short spike in temperature leads to a throttle that then does not properly exit? I ask because running the following more generic version of the original command outputs some interesting lines, this is just a snippet of the full output:

Thermal slowdown is active right now despite cpu/gpu temperatures being in the 50s/60s, causing a 55W throttle to the gpu.

The only way that I have found to correct the power limit without shutting down the computer or the program is by unplugging the charger for a few seconds, then plugging it back in.
