I have been trying to make my DC G5 run cooler, but nothing seemed to work very well. After taking apart my DP the other day, which had a bad logic board, I decided that reapplying the thermal paste to my DC might be a good idea because it is an 8 year old computer and probably could use some new paste. I thought I would share my results with you all here, and I have attached some photos because I know everyone loves to see some good ol' photos. I used arctic silver 5 for thermal paste, and I cleaned the area with 92% iso. I then let the chip dry under a warm lamp for 30 minutes. After putting everything back together I ran ASD to recalibrate the system, below are my temperature results. Temps before: 120F-125F (49C - 52C) at idle 130-135F (54C-57C) running weather software Temps after: 108-112F (42C - 44C) at idle 116-120F (46C - 49C) running weather software Not much paste there! Heatsink with old paste Almost clean! Prepped heatsink with very small amount of AC5, notice the haze color to it Ready to go with AC5 on it. I used smear (using saran wrap). There was a perimeter black plastic around the die which I kept in place What a heatsink Well, overall this was a complete success. I achieved much lower temperatures and more even temps across both cores, before I had about a 5-10F degree spread. I highly recommend it to all G5 owners if you want to cool down your summer time heater.
