• CPU stuck to heatsink
    12 replies, posted
I recently had my FX 8350 die on me about a week ago. So I have been using my laptop since then. I also recently got my RMA accepted by AMD. The one snag I have is because my cpu died I couldn't heat my cpu up in my motherboard. I removed it from the motherboard(which does work btw). Now after examining it off an on for a week I been having trouble removing from it heatsink. I've also been able to remove some of the thermal paste which appears to have harden like cement. I've tried letting it sit in a bowl of 91% Isopropyl Alcohol. Also I've been able to scrap the edge of the paste off carefully with a razor blade and a blow dryer but, I'm still unable to get it to move when I try to pull or twist off. I've also tried heating it up with a blow dryer but it does seem to get hot enough so it's in a paste form and not a cement like form. I wanna know if you guys have any possible solutions for removing it which wouldn't void these [url=http://support.amd.com/en-us/warranty/pib/step2]rules[/url]. Also I'm pretty sure my thermal paste was long past needing a change.

Yeah about that camera phone is bad on pixels. [t]http://i.imgur.com/2qDEgGg.jpg[/t] Basically all the edge of paste have been trimmed.
Take a flat head screw driver and wedge the shaft of the driver under one of the corners of the green PCB, so it's between the PCB and the heatsink. Use the flat head of the driver as a fulcrum pressed up against the heatsink and pry the PCB of the CPU upwards while holding the driver shaft firmly so it doesn't slip. If that doesn't work, get a large pipe wrench and carefully adjust it so it fits around the green PCB part of the CPU. Put some paper towels folded into squares between the jaws and the CPU then start twisting gently while holding the heatsink with the other hand.
Jesus christ.....I knew AMD ran hot but damn...
[QUOTE=JC2Gamer1456;44855191]Jesus christ.....I knew AMD ran hot but damn...[/QUOTE] I ran it at 47-60c on a stock cooler and I never changed the thermal paste. That was my main mistake not changing the dang gum thermal paste. The stock cooler for a AMD FX 8350 is a Cooler Master it's not anything special but my case fans provided good air flow for cooler air to come and hotter air to leave. [editline]20th May 2014[/editline] Also I got it off letting it sit in a bowl of 91% Isopropyl Alcohol for about 17 hours and then with a screw driver apply very small about a upwards pressure in two of opposite corners.

I'm not a professional when it comes to this, but won't the alcohol ruin your CPU if you leave it in strong alcohol for 17 hours? Won't it affect the CPU itself?
[QUOTE=Cyberuben;44857040]I'm not a professional when it comes to this, but won't the alcohol ruin your CPU if you leave it in strong alcohol for 17 hours? Won't it affect the CPU itself?[/QUOTE] It could depending on the area it comes in contact with. However I only submerged the head of the cpu where the paste is. Also this cpu is already dead I need to remove it from it's heatsink so I can get a new one from AMD. I had my heatsink submerged in the alcohol too(I made the decision early on to junk it). I was planning on moving to liquid cooling for better and more stable overclocking. Which is what I plan to buy before I get my new one.
I was going to tell you to put a block of wood against the CPU 90 degrees relative to the heatsink and tapping it a few times with a hammer.
Well it seems that the very hot AMD CPU got so hot that it melted the copper heatsink. This is why kids you buy Intel and for people with a lesser speaking edicate. I AM JOKING

Update to this thread. My cpu passed mechanical inspection and has been shipped back to me a new replacement cpu(another 8350). Few minor things to note I felt it fall in a bowl of alcohol where more than the pins came into contact with the fluid(it was dead already no need to worry). I had 3-4 minor bent pins from removing from my motherboard without it being heated up. I straight the pins very gently and every passed overall.
Alcohol evaporates very quicky, and you can't damage a component that is off in liquid as long as it doesn't sit there long enough to rust or corrode
