Where does one source a replacement cpu heatsink

You will burn out your processor if you run it without heatsink

Remove the heatsink and fan assembly over the CPU.
The CPU is locked in the CPU socket, lift up the locking lever to release the CPU.
The new CPU needs to be inserted into the socket and then lower the lever to lock the CPU into the socket.
Coat the CPU with heatsink compound before fitting the heatsink and fan.

Its possible that the Motherboard connector for the fan is not putting out power. there are CPU fans that use a standard 4pin Molex connector, that is what I would suggest you use.

it is a pretty good chance that your power source is broken, but another one is the mother board. take the source from your other computer and test it on this hp pavilion. if it doesn't start, take the cpu from the other computer and test it on this one, first with its original source and after with the source from the other one (the one with the cpu)

Hi,
the dreaded Blue-Screen of death.
Usually caused by:- Ram Failure ( memory Modules )
CPU Failure ( Processor Failure )
Hard-Disk faulty, not spinning et,c.
Cmos battery fault.
Missing/deleted/corrupted operating System files.

Possible Solutions:- remove cmos battery, from Motherboard for 10 seconds and replace. ( eliminates cmos/bios errors )
remove 1 stick of Memory ( Ram ) and test individually ( eliminates 1 or More Faulty sticks Of memory Or Slots )
remove, CPU Fan/heatsink, remove CPU and re-seat, re-grease with Artic-Silver or similar ( thermal-Compound ) replace heatsink/Fan. test.

Hope this points you towards a Sucessful repair.

one reason that a CPU fan may be running constantly is that it may not be able to cool the cpu down. usually this could be due to dust or debri clogging the incoming or outgoing vents or even dust accumulated on the fan itself or the heatsink.

Usually this problem is caused by a thermal [overheating] condition. Best solution is to open the case and see if the cpu fan is working. If not replace with a new heatsink fan combo and make sure you use a quality thermal grease between the cpu & heatsink. Hope this helps & please rate this solution as fixya. Thanks.

Good news! You don't want the fan to stop running. There are 2 in there most likely- one for the power supply and one for the CPU. Both run continuously to keep the innards at a safe operating temperature. If you want to keep an eye on the temperatures, I use SpeedFan and it'll keep a temperature in the lower right for you to watch.

Thanks for using Fixya.com and please rate this tip accordingly.

i am suggesting you the solution keeping in mind that there is no display is on the monitor.
The max ram that HP Pavilion 6630 PC Desktop can support is 256 mb pc 100 or pc 133mhz.
check if you have installed that amount of ram, if thats correct then check if any continues beep sound is coming out of CPU.

if there is beep try to change the ram slot.the more possibilty i either the new ram is faulty or incompatibel.

try to install the old ram see if it works. if still no display.


install old cpu and heat sink.see what happen ..

then let me know the result.

bye & take care..

ya change that heat sink out get new thermal paste on cpu screw down mobo and everting else tight ok newegg.com sells fans for heatsinks just gotta figureout what soket uuse ok
