Bought and tested, there is clear difference, although not up to my expectation. Maybe like 4-5c reduction on hotspot temp, 3c on core temp.

I butchered the installation, had a hard time trying to separate the plastic from the silicon layer and there was parts where I teared the silicon. Decided to just install it to see how it performs, it seems that it works quite alright.

not much instruction inside the box. already read in forums how putting it in refrigerator will help, but my impatient ass just need to see the improvement after waiting 1 week for shipping.

they have clear plastic and white plastic part. i'd say, release the clear plastic first, things will be much easier.

now after 1 week+ of application, I'm seeing further improvement. The fan RPM down by 100RPM. My GPU much more silent.
