Low boost clocks and high temps in Cinebench

I’ve got A1398 Late 2013 with 2.6ghz i7-4960HQ. Thermal paste apparently wasn’t swapped it’s entire life. In Cinebench it was reaching 95-100 degrees and 2,8 - 2,9 clocks. CB score - 540 or even lower.

I changed the paste with Cooler Master V1 IC Value. And got… 95-100 degrees and 3.0 boost clocks AT MAX. CB score 580 0_0

This model must give about 640! What the heck is that? I didn’t make any nooble mistake I bet, I did everything right. I even reapplied the paste to be sure it’s not my fault. Nothing changed, it works slower than it must and even gets hot while FF playing video.

What could be? Never stumbled upon anything like that

Before CB:

While second run launched instantly after the first

Lets get a better view on things here, install this app TG Pro its one of the better monitoring apps. Wen the system is idle take a snapshot of the main window, make sure you grow it so all of the sensors and fans are visible. The do a second snapshot capture just after running Cinebench.

OK, I think I see the issue. Note the heat pipe Outgoing Air sensors are very low in comparison to the CPU temps when you are stressing the system.

So the heatsink has failed! The coolant within the tube has leaked out. You’ll need to replace it. Keep in mind there is two versions of this system. The IG - Intergraded Graphics (Intel Iris) & DG - Dual Graphics (Intel Iris and AMD GeForce GPU. Make sure you get the correct heatsink.

The only way I know of to tell if yours is truly dead is to use a good weight scale that can measure the subtle difference of a wet Vs dry heatsink.
