What is PWM Phase 4?

Hi, i have run more tests on my pc and found that on shutdown it is beep enabled on my mboard. I have eliminated each beep one by one before it crashes and this is the problem. The temps on phase 1-5 are all set to maximum 125 degrees C and 4 carrys on past this into the 130s then shuts down. What is this and can it be fixed? thanks guys in advance.

Check the PWM heatsink(s) around your CPU socket, one is probably loose.

checked, and they are fine mate. any other ideas?

Try taking them off and applying some thermal compound and try and get a fan blowing on them.

you cant apply thermal compound due to the shape of the heatsinks they are a stupid design, if you put paste on there is no contact made thats why they used pads. Can you get waterblocks for these i may put them on my loop?
