CPU Cooler and CPU
Follow the steps below for removal.
CAUTION:
The CPU cooler on the CPU may be hot after you turn off the power. Wait until it cools
before you remove it.
Note:
When you replace a CPU, you must replace the CPU cooler too because the silicone that attaches the
cooler to the CPU will come off when you take the CPU cooler off of the CPU.
When you replace a CPU cooler without replacing the CPU, confirm that the silicone comes completely off
of the CPU. If any silicone is left on the CPU carefully remove it by using a kind of scraper. To avoid
damage, do not use any metal scraper to remove the silicone.
1. Remove the IM-800 upper case. (See page 9-42.)
2. Remove the CD/FDD bracket. (See page 9-49.)
3. Remove the DIMM. (See page 9-60.)
4. Disconnect the CPU cooler cable from connector J13.
5. Then detach the metal hook from the tab, which is shown in the circle in the illustration
below. Use radial pliers for the unhooking. Press downward on the projection and move it
away from the cooler.
