Gday All.

Installing a Aywun R1-V8 CPU heat sink and cooler on a new GA-EP41T-UD3L and the recommendation is to use TWICE the amount of paste than usual.

I have always installed with the minimum amount, enough to make good contact as the compound is there to fill voids and the metal surfaces should be in as close contact as possible.

Anyone fitted the Aywun? Did you follow the instructions? Was there any problems?

Thanks.

Where does it say that? The purpose of thermal paste is to fill the microscopic pits and cavities in the mating surfaces to push out heat trapping air. It is not to be a layer of goop separating the surfaces. Ideally, if the mating surfaces were perfectly flat, you would have 100% surface to surface contact and no paste would be needed. But until humans can create perfection, and produce CPU and heatsink materials and mating surfaces with zero imperfections or impurities, the use of some sort of interface materials is needed. See my canned text on TIM here.

Oh, and just so you are aware, if this heat sink is being used on a new "retail" version of an AMD or Intel CPU and the CPU came with its own heat sink fan assembly, using a 3rd party cooler voids the warranty!

Hmmm. Never seen that before. Did they supply the paste?

I would not do it but instead, use a good paste and apply the thinnest even layer you can possibly apply. There is just no way a layer of goop can be more efficient at transferring heat than direct surface to surface contact between the mating surfaces. And if you double the thickness, it is likely that is not going to happen.

At any rate, you need to monitor your temps. Your motherboard utilities disk will have a monitoring program (or check for a more recent version on Gigabyte's website). Or, you can try CoreTemp for newer Intel and AMD CPUs, or [url="http://<a%20href="http://www.techpowerup.com/realtemp/"%20target="_blank">http://www.techpower...m/realtemp/</a>"]RealTemp[/url] for Intels. SpeedFan is a great and popular alternative, or you can try Motherboard Monitor. Unfortunately, I have found that these programs often have problems properly identifying and labeling the sensor they are reading. The temperatures shown are as accurate as the inexpensive, low-tech sensors will allow, but it may say System Fan instead of CPU Fan. Fortunately, the programs do allow you to edit the labels, so I use Everest to verify the temperatures (as it is able to put sensor to label correctly), then edit the label in the monitoring program. In Everest, look under Computer > Sensor, then wait a couple seconds for the readings to appear. Unfortunately, Everest does not minimize to the system tray to show real-time temperatures, otherwise, you could use Everest instead of the others.

Hi.

Thanks for the info.

Done a fair bit of searching this topic and can"t find anybody who has had problems.

Yes they did supply the paste which I would not have used.
I always try to get good contact sometimes lapping and buffing the heat sink, but not for this build.

Lapping if great - if you have the proper tools. Proper lapping requires "precision" tools to "machine" perfectly flat surfaces. The thumb and eyeball are not precise. :)

Too much paste rarely does cause problems - but it can. It does not provide optimal heat transfer and may result in a few degrees higher heat. Unless high to begin with, they would still be within acceptable limits. The most common problem I've seen is the mess too much paste causes after the HSF assembly is clamped down and the pressure causes the paste to run over the die edge, onto the socket or motherboard. Not good.

Hi.

Been a long delay, mostly due to dead board, which got lost, etc, etc, story here, http://www.geekstogo...st&f=9&t=275901

The "use twice as much as usual" seems to be the advice becuase of using a heat sink whick has a much larger

Hi.

Thanks ofr your help so far.

Have finished the build and will post the specs and test results later.
