Hello,
First my story, then my question:
My GTX 560Ti graphics card has gotten louder than I remembered after coming back from my exchange semester (not having used it for 5 months).
So on Friday I decided to vacuum it from the inside, taking care to shut down the computer, remove it from the grid, not to touch anything with the vacuum and preventing the fans from turning (to prevent them from inducing anything anywhere). The GPU is barely reachable in the chassis, so I didn't really get to clean it a lot.
The computer worked fine on friday. (for 3h of playing Guild wars 2)
On Saturday, my computer shut down repeatedly: Black screen, power-led suts off, then on again, with only some fans running, including the graphics card fan. (Hard-drive led not lighting up). My interpretation was that some dust was dislocated by the cleaning and ended up worse than before. I donwloaded some sensing program, which showed the GPU temperature at >85°C during play, with the fan speed still at ~40%.
The GPU case geometry is a lot like in the vid, so I thought I probably should clean it from the inside: http://www.youtube.com/watch?v=74DLrJSE3BI&t=0m57s
The inside of my PC looks like this (pic not taken by me):some guy's computer (also acer predator with GTX 560Ti
I discovered I could not remove the black case, as it is one with the whole fan/heatsink unit. But some more detailed blowing (lens cleaning blowthingy for cameras). This got an ~5°C improvement in temperatures, but still didnt seem sufficient. Some people recommended manually increasing fanspeed with MSI afterburner (didnt touch anything else). Having done this I was able to play without issues for some time, though with increased noise from the recommended fan settings in the program. I once had a screen-freeze when there was lots of stuff going on (had to restart, never had this before), but was able to play normal content for 2 hrs afterwards.
Now on Monday, my PC had a freeze (sound+graphics) and at the next try a black screen with cooling afterwards. Updated drivers and switched of MSI afterburner, got a freeze again.
Now my questions:
Do I have any chance of fixing this problem by changing the heatsink/fan? I cannot really clean mine atm., but there definitely is airflow, so basic functionality should be ok.
I was thinking about something like this (please excuse my German).
The chassis has air inflow through the side (passive) and one out-facing fan to take care of the processor's and probably the power supply's heat. The GPU vents through a few slits next to the monitor-plugs. Does it make sense to use abovementioned cooler here?
monitoring stuff claims my GPU to be running below 50% load, but the cooling arrangements are limiting it there, so yes, I really want to get a new fan.
Might my power supply, against all hints towards the GPU, be the problem? Do I need to consider my power supply in choosing a GPU fan?
I would be very happy if you could help me here..
Yours,
John
