Cleaning gpu out

I recently opened my 4890 up to clean the dust it as it had huge ammounts, the front of the heatsink was like 100% blocked, but as i had no rubbing alcohol left, i used goo gone on the processor to get the paste off as it was stuck on by ALOT, i was wondering if this was okay? or should i redo it with my ocz freeze, and is using 1yr old ocz freeze okay?

my temps are

xfx 4890 oc, and 45% fan speed

40-45c idle
50-62c load

75% fan speed
35c idle
55-60c load

32c idle
55c load

  1. temps sound fine to me
  2. If you cleaned the old paste off you need to reapply new paste for sure. Aftermarket paste can make quite a difference. IC Diamond 24 made my GTX460 run 4C cooler at idle and 7C cooler at load than the stock stuff. Free overclock.

    As long as it is not dried out I say year old paste is fine.
  3. Hi,
    normally I use good quality silicon grease from Dow Corning.
    You can buy that from the reputable RS.
  4. i used ocz freeze. thats not stock paste, im saying i removed the old paste with goo gone.
    and put ocz freeze on, i was wondering if the goo gone harmed it any.
  5. No, as stated above those temps look fine. I doubt you hurt anything.
  6. are these temps good for 24/7 use or should i get em lower
  7. your temps are fine, don't worry about it, go back to killing zombies
