Thick paste, great for GPUs.
I'm currently using this paste on a Radeon HD 7990 with the reference cooler.
PK-3 is much thicker than other thermal compounds I used in the past. Application isn't very difficult but does require more pressure on the plunger. There is a plastic spreader included, but I did not use it. Thermal performance is very good, typically running around 50C over ambient, reducing load temperatures by about 3-5 degrees over stock paste. GPU temps peak at about 86 on very hot days.
One of the main advantages of PK-3 over other pastes is the resistance to pump out. On my GPU I've had multiple pastes lose thermal performance within a week as thermal cycles gradually squeeze the paste out between the die and cooler. So far, PK-3 has not had any issues. Thermals are just as good as the day I applied it.
Overall I'm very satisfied with the performance I'm getting. I think PK-3 is a great choice for bare die applications where pump out is a concern, such as on GPUs or laptops.

Still a great choice.
1 of 1 found this helpful This has been my go-to aftermarket cooler even after all these years. I've found that the EVO outperforms the more recent versions of the 212, such as the 212 Black Edition.
Temperatures are pretty good, I'm pushing 1.250V through my i5 4670K to maintain 4.3GHz (I got a below average chip). Load temperatures in games and normal programs are around 65C max, while synthetic stress testing will see around 75C. My ambient room temperature is generally around 26C.
Noise levels are a bit high when the fan nears maximum speed. It tends to generate a howling sound above 80%. However, under normal loads the fan is quiet, and still delivers sufficient airflow to cool my CPU.
Mounting isn't as easy as some other aftermarket coolers out there, but it's totally manageable. Note that access to the rear of the motherboard is required to mount the backplate, so depending on your case configuration removing the motherboard may be required.
The thermal compound included is decent, but for high voltages/OC I would recommend something better. They do give you a second fan bracket, but I didn't see any improvement in cooling performance with a push-pull configuration. Still, it's nice to have that option.

Excellent upgrade for an older PC.
I bought this card to upgrade an old OEM machine I had lying around. I was looking for something reasonably capable with low power consumption and was inexpensive.
Gaming performance works for what I throw at it, mainly older titles from around 2008 such as Modern Warfare 2, Witcher 1 or Fallout 3. It's not blazingly fast but it's a significant step up from integrated graphics or lower end dedicated GPUs such as the HD 3650 it replaced. There are faster compact, low power draw cards such as the GTX 750Ti, but I found they also cost quite a bit more.
Power does require one six pin connector, but total power draw is rated at 80W which is fine even for OEM power supplies. I'm running this off of a PSU that puts out about 360W of 12V power without any issues. The GPU doesn't generate much heat, and the cooler gives low temperatures and is whisper quiet. I'm running this card inside an OEM case with just a single 80mm case fan without any overheating issues.
Driver support is a strong suit of the 7770 compared to older AMD/ATI cards. It uses the same drivers that new AMD cards are using, while the previous generation 6000 series cards have the most recent compatible driver that's from early 2016.
It isn't the most powerful compact GPU out there, but for an old PC it's a significant upgrade that doesn't break the bank.
