the include 3m type tape inside the heatsink is not strong enough. Once the PC is in use, the heatspreader falls off.

Bought silicone sealant, but I see the included tape is still there. The tape still is able to adhease the plastic, when I push it back in there, but it's not very secure against heat and gravity.

What's my best course of action in making my ram's rgb diffuser plastic from falling off as soon as the PC case getsa warm?
