The following tip is meant quite seriously, because you can collect plus points with it. But what you have to keep in mind, I tell you in a small practice video in the Friday edition on our YouTube channel, because it shows and explains itself faster than you could describe it in many words awkwardly.
Of course, each of the VGA water blocks has its own peculiarities and not always you can realize everything 1:1. But if even the big manufacturers apply the thermal guide on the radiator (leave), then this is not only for logistical and technological reasons. The larger a GPU or the more sensitive an interposer is, the higher the RMA ratio can become if not everything runs exactly. And that's what it rarely does.
And who doesn't know the sloping pads when you turn the PCB over so you can screw it on the block? Annoying all the time! This is now over, because manuals are only human beings and therefore not free of mistakes. Incidentally, the application of the thermal paste shown in the video is quite sufficient in terms of quantity, because even then paste squeezes out of the gap between the GPU and the cooling block. During the subsequent removal, no air pockets were visible. That is the way it must be! 😉
If you then have your own thermal guide pads, you can start by using the areas not provided by the manufacturer such as coils & Co. test whether there is not a pad in between. Unfortunately, many manufacturers save them in the wrong place or only take action when the review has shed light on exactly this circumstance and found it to be negative. Reaction instead of action, but unfortunately nothing new. With this in mind, I wish you a nice weekend and don't cover you too much with thermal paste. This is poison for textiles. 🙂
