Time For Thermal Paste Set In?

bumblebee_tuna · 10-02-2006, 03:57 AM

How long does it take for thermal paste to fully set in and create optimal heat transfer? I wanna know if I have applied it right......

Generally around a week

One way to see a good bond after first applying the new paste is to let the system run for a few hours to heat things up. After that the bonding starts as the hsf and cpu start cooling. Generally a thermal coat takes upto two weeks to see a full bond. This will depend on how often the system is run.

what are the procedure to reapply or set a new HSF? Precautions and whatnot...

So would temps of 40-44C-ish be good temps per say after a fresh application?

Is that temp reading when the machine is idle and hasn't been running for long? Or after a hard core usage and having been on for many hours? As my machine (spec in sig, similar to yours processor and HSF wise) normally idles at around 37C when having been on for many hours and after a good gaming session.

For reapplying a new coat you would first have to thoroughly clean off the old paste even if it was recently applied. This insures a clean surface for a good bond to take place. Something lint free like an old bandana or rag would be used there with some denatured alcohol for a quick dry.

Let's see when the cpu was first run on the new board here for much longer then 4hrs. the overheat protection shut the system down at 60C where it was set. That was right after applying AS5. This is why a good 4-5hrs. max is done first to allow the first cool down to start the bonding. Over the next few days the temps will start to drop to where you will see them normally if you have a good seal formed between cpu and sink.

This is where you have to keep a close look on temps to see if anything was done wrong. You can always reapply and reseat if the first coat bails out on you provided the cpu didn't cook in the process. On Asus boards the Probe I as well as Probe II are great to have onhand. SpeedFan is one freeware good for general use on a large variety of makes and models.

Yup, PC eye has got it

It reminds me of bedding in new brakes. You want to heat them up, then cool them down, to ensure proper bedding/seating, etc. If you don't run them hot enough before they cool, then you wasted your time.

On the old cars it was described as the "breakin time" for engines in new cars coming off the lot for the first time. That first time on the build here was a test to see if the overheat protection circuit would work. Upon reaching the threshold of 60C for the 65C max temp on the model cpu here the system saw the sudden shutdown.

In a few days time the idle temp was about 33C with the Zalman CNS9500 model cpu cooler. In the last few months and after running all day and night the idle is roughly 35C with the max load on it seeing a top of 43C.

Paste can make that much of a difference?
