Thermal Paste Need to know how critical thermal paste is to installing new CPU? I neglected to get some along with my new CPU and I can't find any locally. Is there any house-hold stuff that can be substituted?

    Found thermal paste at my friendly local Radio Shack for just $3.16. Thanks, anyway.

From the word itself it is a thermal paste that can hold the CPU and iot helps out to prevent the heat coming from the processor, when the cpu fan operate/spin it also that helps that processor to cool down.

You may try a toothpaste as a substitute for it you will need a "white base toothpaste" just put only a small amount into it.

Let me know for any clarification

OMG! Do not listen to Jhulmar Ocampo,
That is a sure fire way of frying your new processor.
Only use high quality thermal compound (not your radioshack stuff you have got now)
You might think you are saving a few pennys by buying cheap. But you have to ask yourself this. Is it worth frying my new, hundreds of pounds/dollars worth of cpu because of saving a few pennys?

Thermal grease is definitely a MAJOR part of a modern computer's cooling system.
Do yourself a favour and get a top name brand e.g. Artic silver or the ceramic version the same company does.

Thermal paste is needed because the surface of the processor and heat sink are not perfectly smooth. if you examine with a high power microscope, you will realize there are small hills and valleys. With no thermal paste, the heat transfer is limited to the small contact points that result. With a filler, that is heat conductive. a thermal heat path is formed across the whole heat contact area not just the high spots.

at first the thermal paste was silicone grease. anything like this will work, even Vaseline. Later the silicone grease became white, this was because of the filler Zinc Oxide. a good heat conductor and poor electrical conductor.

bottom line the thermal paste greatly improves the ability to draw the heat out of the processor.

Maybe you have encountered problems like your computer freezes suddenly and you try to find solutions to it by troubleshooting your hardware or software installed. And after troubleshooting for hours and you are 100% sure that all your hardware and software are working just fine.

But you have never tried to look or never guess that between the Heat Sink or CPU has a solution that is put between them to be able to cool the processors/components. It is called Thermal Paste (other names: thermal grease, heat sink paste and etc.).

Thermal Paste helps the cooling off of components and draws heat away from heat sink/cpu. It is really a big help and can increase efficiency in your computer systems.

If you haven't try or see Thermal paste in your computer, try opening your system it is found between your heat sink and cpu, the substance that is applied between them.

It solves computer freezes.

New thermal paste after a month

Anytime you take the heatsink off of a CPU you should remove and replace the thermal compound. If you didn't, then there's no need to worry about it.

In thermal my system fan speed has a red dot what does this mean

I believe this means you need to upgrade your CPU cooler fan!Usually it would react this way when a thermal event is takin place.In which case,your PC is getting bad thermal readings,so make sure you have proper air flow in the computer as it may be the reason for your thermal issues.Otherwise you would have to manually remove your CPU,remove the current thermal paste and apply new thermal paste carefully in the designated area specified by the manufacturer!-Hope this helps!!!-CB

Cpu over temperature error cpu temp : 39 to 101 mb temp : 30 to 100

First step would be to check all cooling fans are running correctly. Second blow out the dust and debris from inside the computer. If the cooling fans are not running correctly you will need to replace them. Thrid have you added any new hardware or have cables that would interfere with airflow? If so move things around so you have good air flow around the processor. Finally (before we get into the professional portion) you might try adding additional fans to the case, there are fans that will go in a drive bay to help improve air flow.

CAUTION!!!! The following steps should only be taken by a competent professional:

1. Check the heat sink, is there thermal paste leaking out around it (too much paste was used). You will need to remove the heat sink, clean up all thermal paste and then remount the heat sink with a small amount of thermal paste.

2. Remove the heat sink, is the thermal paste dried up? If so, inferior thermal paste was used. Clean up all the old thermal paste with alcohol, replace the heat sink with a small amount of good thermal paste.

Of course if you are running the computer in an 80 degree room, that will affect temperature too.

Hope this helps.

Which procesor heatsink and fan can i use for this motherboard

You absolutely must use thermal paste to attach the heat sink to the CPU. If you run your computer without thermal paste, you can ruin your CPU in just a few seconds.
There are many manufacturers of thermal paste on the market currently and each package should have instructions on how to use it. If no instructions are included with the paste, check the manufacturer

First you will need to know what kind of socket you have on your motherboard, so you can purchase the correct CPU for your replacement. Intel and AMD have lots of different socket sizes so don't overlook this point. If you have the CPU that you are going to replace, all you need is a screwdriver, thermal paste, and CPU fan.

1) Open the case cover with screwdriver, and open side panel to locate CPU.

2) Using a screwdriver or sometimes just release clamps to take off the CPU fan.

3) Release lever on the side of the socket to release the CPU.

4) Pull out old CPU and install new CPU, (Be very careful not to bend the pins on the CPU.)

5) Put small amount of thermal paste on top CPU.

6) Replace CPU fan and connect power to the fan, replace cover.

Now in a perfect world this should be it, but if you upgraded you CPU you should go into you BIOS and check the settings for your CPU. To make sure the voltage is correct.

This is a question regarding the Intel processor's internal thermal solution. I have a Core i7 870 processor. As a sidenote I've used it a few times to start the computer and it's functioning, but I can't...

If you have already wiped some thermal compound paste fro the processor then I reccommend you to wipe it completly from the heatsink of the cpu and the heatsink itself. The reason to this is that if you plan on purchasing another type of compound thermal paste in which have more conductivilty then you want to get the most out of it. Do not attempt to run your cpu without any thermal compound as you will damage the cpu from overheating.

Replace heatsink fan on CPU.

The thermal paste should be cleaned off. Clean the CPU and heatsink fan with a dry cloth, which should remove the paste quite well. It is simply a viscous liquid and should not require scraping.

You should replace the thermal paste when installing the new fan. You can purchase it at your local computer supply store. Simply place a small dab of it on top of the CPU and then install the fan.

If you try to re-use the existing thermal paste, you will not get reliable heat transfer from the CPU to the fins.

My comuter won't start up properly. It stays blank right before the log in screen at start up. It shuts down automatically when I play certain video games.

Ok this could be a CPU Issue, after a while the thermo paste on the heatsink which is on the CPU under the fan the paste will dry out and when it does the cpu once starts working under load due to the games being played will shut down to protect itself and the board.

What you need to do or get someone to do it for you take out the Heatsink reapply thermo paste on top of the CPU (by the way thats what I call it) may be known in your region as Thermal grease (also called thermal compound, heat paste, heat transfer compound, thermal paste, or heat sink compound. If you need more help let me know
