Asus TUF 4090 questionable cooling choice?

[Rym]

Asus TUF has no Inductor, Capacitor, Memory controller and very bad memory cooling (no heat spreader for memory).

 

Is this an issue for customers? Will the cards fail faster because of this design choice?

Capacitors and inductors should never need cooling and the RAM on that card still runs cooler than the FE so should be fine.  It was far worse on the 3090 when half the RAM was on the back.

 

 

I certainly hope so, its the model I'm primarily looking out for.

Capacitors and inductors don't need cooling.

Memory controller is in the GPU die so it's cooled.

Mosfets and VRAM are cooled as you can see on the pictures you posted. There are thermal pads that contact them when the cooler is mounted to transfer heat to the cooler.

They are referring to the fact they are thicker thermal pads so less efficient (as shown in the video) than having a cold plate and using thinner pads.

 

Most electronics will age quicker when running hotter, but I doubt its by a significant amount.

Thermal degradation is significant when you run out of spec. This card will run still with big headroom before reaching the max temp in the spec.

Indeed, and given the FE card runs its RAM hottest and clearly is still within spec, anything cooler is well within acceptable limits.

I wouldn't be surprised if the VRAM is rated up to 105C so around 80s is no big deal.
