Leroy Elliott's answer is incorrect. The purpose of thermal paste or "grease" it to help with the transfer of heat from the cpu to the heat sink.
Without this grease or if the grease dries out the heat sink can not do it's job efficiently

To insulate the cpu from the motherboard and dissapate heat

  • whitcwa Jan 04, 2011

    It is not designed for electrical insulation. It provides better heat transfer to a heat sink which does dissipate the heat.

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.

Hello, I have a Kenmore Dryer 90 series... We are in a Town house on and the Dryer is on the 2nd floor and the vent goes up vertical for about 12 ft with a 45 then to the roof... my dryer gives off heat...

To check the thermal fuse - You can bypass the thermal fuse (just connect the 2 wires together) for testing purposes only.
To check the thermal cut-out - You can bypass the thermal cut-out (just connect the 2 wires together) for testing purposes only.
To check the thermostats for continuity - - You can bypass the thermostat (just connect the 2 wires together) for testing purposes only.
To check the Element: Try removing element and physically looking at the element wire for a break in the wire.

More than likely it is the heating element.Remove the front lower panel.While the dryer is running look inside at the bottom,if the element is getting hot you will be able to see it.If the element is not hot,replace it.

Dryer drum works but does not heat. Everything else works. I have checked the fuse and I have made sure it is not on air dry.

THERMAL FUSES MAY BE THE CAUSE OF THIS In recent years the makers of dryers are using thermal fuses to let you know something is wrong with your dryer. They are generally non resetting and have to be replaced. The thermal fuses are located on the heater element housing and should read continuity if read with an ohm meter. Most blown thermal fuses are the result of vent/air flow problems or a grounded heating element. Follow the diagram below to see how to check the continuity of the switch, and look closely at the switch to see a fairly close idea of what you are looking for, ok

OR it could be a thermostat.
Cycle and safety thermostats-read them with an ohm meter. Should show continuity .

or lastly, it might be
the Heat elements-Test heater element with an ohm meter. You will read continuity across a good element ( 8-12 ohms is an average element ).

IF you do not have an OHM-METER, then you can check these issues by following the directions below:

To check the thermal fuse - You can bypass the thermal fuse (just connect the 2 wires together) for testing purposes only.

To check the thermal cut-out - You can bypass the thermal cut-out (just connect the 2 wires together) for testing purposes only.


To check the thermostats for continuity - - You can bypass the thermostat (just connect the 2 wires together) for testing purposes only.

To check the Element: Try removing element and physically looking at the element wire for a break in the wire.

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.

Thermal Paste

Hi,

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

I own a Maytag Dryer that has stopped working properly: Model LER6620PQ0 Serial MS3647251 Type DWJR-ELE-2406028-FM54 On all cycles, the timer moves until it is ready to stop. At that position, it...

Dear Paireyes,

Things that can stop electric dryer from heating are as listed: house fuse or breaker, heating element, burnt wire, thermostat, thermal fuse (not all models), motor heat switch, timer, selector switch, burnt power cord/plug

To check various points here are the simple tips:
  1. To check the thermal fuse - You can bypass the thermal fuse (just connect the 2 wires together) for testing purposes only.
  2. To check the thermal cut-out - You can bypass the thermal cut-out (just connect the 2 wires together) for testing purposes only.
  3. To check the thermostats for continuity - - You can bypass the thermostat (just connect the 2 wires together) for testing purposes only.
  4. To check the Element: Try removing element and physically looking at the element wire for a break in the wire.

Here is the link for the dryer and how to disassemble the dryer along with the images:

Let me know if that helps. All the best :)

Power supply to xbox 360

2 red lights on part 1 and 3 indicate the the console is overheating, the most common problem is the thermal paste.

You need thermal paste or it will overheat instantly, using cheap thermal paste or not using enough thermal paste will also cause problems. Use good quality paste and apply enough to make contact. You don't want to use too much, but if you use too little it won't make good contact with the heatsinks.

If you've done this before then it shouldn't take too long, but if you haven't then just take your time. You don't want to put too much on at first so do it bit by bit.

If you're still getting this error after correcting with thermal paste then the only suggestion would be to contact Microsoft but then they might not take the 360 after you have already void any warranty by opening up the console.

What is a thermal paste?

hi im josh in cebu phils. may i help you? Thermal grease (also called thermal compound, heat paste, heat transfer compound, thermal paste, or heat sink compound) is a fluid substance, originally with properties akin to grease, which increases the thermal conductivity of a thermal interface (by compensating for the irregular surfaces of the components). In electronics, it is often used to aid a component's thermal dissipation via a heat sink. you can buy this in any pc hardware distributor. i looks lihe an ointment. Good luck i hope i helped you.
