I'm trying to find a replacement fan and heat sink to fit my 500 GR desktop.The only thing marked is the fan which is from coolermaster.
On the other side of the fan it says Protechnic Electric.
12 volts and 0.54 amps.
There are 4 screws that connect the heat sink to the motherboard . Most if not all the fans and heatsinks i've seen have some sort of clamping mechanism .
I'm not computer savy and would appreciate any help that anyone can give me, especially on how to measure the heat sink and compare it's dimentions to those i've seen for sale online.

Case fans ? there are/should-be, 4 screws holding them to the case.
CPU fans ? YOU should not be attempting to remove It. They are part of a Heat-Sink / Fan combination....with the Heat-Sink being attached to the CPU via Thermal-Paste. If you are trying to change the CPU...you may not be able-to. Some are not designed to be separated from the H/S. You would replace the entire H/S-Fan assembly.
Yes you can, remove the cover off the desktop computer to get access to the fan and heat sink over the CPU. Use a stiff brush to loosen the dust off the fan and heat sink and vacuum the dust off the fan and heat sink. You may need to use a can of compressed air to blow the dust off the fan and heat sink then vacuum the dust out.
Replacing the fan on the CPU or the GPU, Graphics card, is actually very simple and the fan will run about $20 to $25 depending on what type of fan you get and where. Aside from a new fan you will need a small tube of heat sink compound. The fan just clips on to the CPU. Make sure you get a fan that is designed for your CPU type or it will not fit properly. For instance, if you have a P-3 CPU you can't fit it with a P-2 Chip or P-4 chip, they won't mount correctly and subsequently they won't work. When you go to Best Buy or the computer shop your to buy your part tell them what type of CPU you have and that you want the cooling fan and the heat Sink Compound to mount it with. They will be able to direct you to the proper fan Type. Also, while you have it opened up take the opportunity to use canned Air to blow the dust out of the machine. If you are doing what is called Over Clocking it is important that you know you may have burned the CPU out as this causes the CPU to heat up more than it would if you just had it installed for the proper speed. The old fan will be difficult to remove because the old heat sink compound will have formed a bond between the fan heat sink and the CPU itself. If you have to do any prying to remove the old fan make sure you do so carefully and make sure you clean the old heat sink compound off the CPU before you try mounting the new fan. When you apply the new Heat sink compound you want to place the compound in the center of the CPU and let the heat sink spread the compound out in a thin layer. This compound needs to be spread evenly so it forms a good bond between the Heat sink and the CPU itself to properly transfer the heat from the CPU to the heat sink so the fan can properly cool the CPU.
Hope you can open the CPU and check the CPU fan. Try unplugging the fan power cable on motherboard and inseting again.
If it doesnt solve it, take out the fan (attached to the top of heat sink. Dont take out heat sink) and try with a battery of some 6 volt. Red +ve Black -ve. If it doesnt run, you need to replace that fan.
How did you clean it? The last one I worked on had the fins of the Heat sink totally blocked with dust. This will make the fan scream trying to push air thru the heat sink to cool the processor. If it isn't cooled it will shut down in short order. You must BLOW it out. Use a pressurized air can. Better if you have a compressor with a nozzle.
The other issue may be the interface between the CPU and heat sink is defective. Heat sink moved or become loose.
Of course by this time the processor could be dead also.
This is a difficult problem because I cannot determine the exact cause because of limited information.
This problem will need to be solved by trying one thing at a time.
Do not do all these together.
1. Reseat the RAM.
2. Remove the RAM and get it tested at your friendly computer store.
3. Reseat the hard disk
4. Run a virus scanning program on your computer/laptop
5. Check the fan to see if it spins freely, if not replace the fan
6. Loosen the dust from the fan and heat-sink assembly and remove/vacuum the dust.
7. Try removing the heat-sink, remove the old heat-sink compound and apply a new coating of heat-sink compound to the CPU and re-attach the heat-sink to the CPU.
8. Do a system repair with the Windows installation CD
9. If nothing works then re-install Windows, plus the laptop's device drivers and your programs.
You may need assistance from a computer savy friend to help you. Let me know how things work out.
Whether this is a laptop or desktop you didn't say but it only matters in how hard the repair is. If desktop you can replace the CPU fan. They are usually clipped or screwed ontop of the CPU. Usually the heat sink will come off with it. You'll need to buy an exact replacement and a little tube of heat sick compound. Once you have a new one reverse your steps except first put some heat sink compound on top of the CPU. If this is a laptop then take it to a reputable repair person. Replacing laptop fans requires stripping down the machine.
Hi, All the factory fitted CPUs are having such heat sinks as previously u were having. Check on the backside there will be small plastic covers where screws fit these could be removed by screw driver but u can purchase that heat sink or can use previous heatsink as well if it is working.
