View Full Version : Thermal Grease Cure Time

I just installed a new Zalman 9700NT using the thermal grease that came with the cooler.

I read that when installing a new CPU HSF, it takes time for the thermal grease to settle. How long is this cure time and is there any special way to speed this up?

Depends on the TIM. Many have no curing time. If I remember right 100 hrs of 8 hr usage,, turn it off, use it the next day etc. No worries if your temps are good anyway.

If bad, we need more info. CPU/OC how much and voltages/Ambient temps/case air flow/case type/CPU cooler and fans used/ fan speeds.

Make a sig with most of the info, easy for us to reference.

For reference, Arctic Silver 5, a silver-based compound, need approximately 200 hours of work to be 100% efficient.
Just leave your pc for about 4,5 days of constant work, that will do the job.:up:

My components: P5E-WS, Q6600-G0, 2x2GB OCZ, eVGA 8800GTS-512MB, WD-750GB, P182, 2 x DVD-Writer. All SATA devices. I installed an extra 120mm fan in the front middle cage. All 4 fans set to low.

I just replaced the Freezer Pro 7 by a Zalman 9700NT yesterday.

Monitoring software: CPUID, CoreTemp, Prime95.

CPU: 2.4GHz @ 28.8 GHz, CPU voltage (CPUID): Idle: 1.192V, Load (Prime95): 1.16V

Core temperatures with Freezer Pro 7:
Idle: 38-40C
Load: 58-60C (after 3 hours of Prime95)

Core temperature wuith 9700NT:
Idle: 36-38C
Load:53-55C (after 6 hours of Prime95)

By changing the HSF, I was hoping to get more improvement than 5C in load conditions. Maybe the Zalman thermal grease has to be burned in!

There is a caveat. They specify several cool-down cycles in the 200 hour period.

That's why i've said 4,5 days which amounts to about 120hrs of work..:)
