"Initial batches of ROG Strix 5700-series graphics cards were built following AMD’s guidelines. After receiving user reports regarding temperature issues, we performed extended R&D testing to find the optimal PSI range for our graphics cards without compromising GPU reliability," ASUS says.
What exactly did ASUS find? ASUS plotted it out on this graph...
Accoridng to ASUS, during the design phase of new graphics cards, AMD shares documents with its engineers that outline specifications and tolerances for things like this. And in this case, AMD recommended a cooler mounting pressure of 30-40 PSI. That's what ASUS used on its initial batch of Radeon RX 5700 XT and Radeon RX 5700 cards.
"All ROG Strix Radeon RX 5700-series graphics cards shipped from January 2020 forward feature new screws that increase cooler mounting pressure to 50-60 PSI, resulting in improved heat transfer from the GPU to the heatsink," ASUS says.
Therein lies the optimal range, according to ASUS. Why this was not caught beforehand is a good question—it's easy to blame AMD, but this is really something that ASUS should have identified before the initial batches went out.
In any event, cards with new screws that apply the proper amount of pressure are already shipping. If you happen to one an ASUS ROG Strix card from the initial batch, ASUS says you can "contact your nearest ASUS service center starting in March of 2020 and we'll happily perform the upgrade for you."
