Hardware PS3 slim glitched picture problems

[DaFixer]

Hi since some time I got a nice PS3 Slim with redux 4.76. I make hole for the fan and add new heatsink pase for the CPU/RSX. I set Webman to cool down my below if it go over 57F.
All things worked great and 2 days ago I playing some games, but then the hole screen got glitched.
Then I shutdown and power on my PS3 Slim, and then the PS3 glitched again in the menu.

I let it alone for a day and a day later try again to play a game, I played Minecraft,Fighters Climax and Dragon Crown for some hours and still no problems.

But today I want play Darkness II and it glitched again
When turning on I got a black screen, and 20 min later I try it again and now it works again.

But I want to are there any tips to fix this or my PS3 is dying?

Same problem as you man, my Dark Souls SOTFS has the glitchy graphics such as these

I also tried putting Webman to 60% fan speed, annoyingly loud too and these graphics still persist. Though other people suggest putting the games in internal to eliminate the problem or reinstalling the game data.
