Testing the Temperature
Quite a couple of folks have commented that I used method an excessive amount of thermal grease (compound) and that the quantity I used would trigger overheating. I disagree with this view. So in an try to offer some sort of proof, in some way, I made a decision to watch the temperature for a couple of weeks with SpeedFan v4.44. Then to take the laptop computer aside once more, clear it up, utilizing the steered alcohol wipes technique, and exchange the thermal compound. This time I might use a skinny quantity. I might than assemble every little thing after which monitor the temperature once more. I adopted the identical course of as earlier than with the slight steered modifications. This paperwork that course of.

According to the CPU chip specs for a LF80537 T5500, which is a Intel Core 2 Duo Mobile, the Minimum/Maximum working temperature (°C) is zero – 100°C. The most working temperature of the CPU was 65°C earlier than I began this course of. After I accomplished the method the utmost working temperature was 60°C. It appears I may need utilized an excessive amount of thermal compound however not method an excessive amount of to trigger overheating. Just an excessive amount of as in wastage. It would appear as if extreme quantities of thermal compound might trigger your system to warmth up barely extra and whether it is operating near the utmost allowed temperature it’d trigger overheating. It prompted a 5°C enhance in temperature in my case however this isn’t particular as a result of it was not a managed scenario. The enhance was not sufficient to trigger overheating, however sufficient to infer that extreme quantities of thermal paste might enhance the temperature. The pictures comprise a step-by-step information of what I did.

Notes: Wipes

I discovered the alcohol wipes labored horrible. It smeared the thermal grease throughout and simply created an even bigger mess to wash. It might be as a result of the earlier thermal grease was al dried out and flaked off properly. This thermal grease was moist and sticky. It smeared too simply. On the GPU there are very small resistors or parts and the wipes smeared the thermal grease throughout them after which saved getting caught in them.

If I have been to do that instructable from the beginning over once more, I might use much less thermal grease from the beginning because it does make a distinction regardless of how slight, however I might not use the alcohol wipe.

Update 2013

I’ve been ripping Intel CPUs out of laptops and desktops and changing the thermal compound (grease) for years now and have observed that on the older Intel CPUs the thermal grease was used liberally. However, on the newer CPUs the compound is sort of skinny. I’m wondering if it actually issues that a lot or is it price saving to have a really small (tiny) quantity of compound in between the CPU and the cooler (warmth sink)?

Here is what Intel itself says about the right way to apply thermal grease to a CPU. What you’ll learn will shock you as a result of there isn’t any point out of layer thickness and no point out of spreading it round. To let you know the reality it states that you just blob every little thing within the centre of the CPU and the stress of the cooler (warmth sink) on the CPU will decide the thickness, squeezing out all extra. I believe I additionally talked about one thing like that in one among my feedback. This info comes straight from the CPU producer, and they need to know. Read for your self at:

I’ve included a number of the pictures from the Intel web site for reference.
I’ve additionally changed the thermal grease (compound or interface materials in case you are from Intel) on many secondary chips like built-in GPUs on motherboards by releasing the cooler (warmth sink), cleansing each surfaces, apply thermal grease and exchange. Once you know the way, you’ll be able to exchange the thermal compound on virtually something.

Update 2014

Many individuals are nonetheless suggesting I’m utilizing an excessive amount of thermal grease. I need to convey the next to the eye of those folks. I’m utilizing a non conductive thermal grease. It doesn’t conduct warmth in addition to the conductive thermal grease however doesn’t harm parts when it is available in contact with them as a result of it doesn’t conduct electrical energy. Cooling has to do with eliminating extra warmth, so the thermal grease is just one a part of the answer. The warmth sink, fan and airflow are the opposite components. You might have a CPU that doesn’t have properly utilized thermal grease however has a incredible warmth sink and airflow throughout it and the system won’t ever overheat. Here are some hyperlinks to different sources which I discovered very useful in understanding overheating, thermal grease, followers and airflow.

I hope this helps everybody perceive extra about what causes overheating and the right way to resolve the issue.
