OTOY Forums

I have read online a bunch of times about heating issues with the RTX-series of cards in gaming.

My question is with Octane, is it a problem?
Because while a card might run hotter compared to other cards, it may not necessarily mean it is running too hot to function.
Would appreciate any thoughts or experiences, thanks!

blower style 2080ti seems to be way more noisy under load, what means that cooler should work much more hard to keep it cool enough. Putting 2080ti in the same loop with 1080tis new card seems to run at least 10C more hot than the hottest 1080ti (all cards use EK full cover waterblocks and cooler with oversized MORA3 rad with the best fans on the market). I might have put too much thermal paste, card might be more thirsty, but in general that seems the case that others (like Sebastian) noticed as well. Overall it's more powerful and more power hungry card, meaning it will have more heat to get rid as well.

Hey Tom, thanks.
In your experience does it perform well, or is it hampered by the heat.
ie - does the card get to exploit its power and remain at its max clock, or does the heat wind up capping its power prematurely?

Before I had water-cooled my Titan Zs, they had that issue. They would run awesome but then they would get above 84-85C and that was it, they would then down throttle and performance dropped.
Where as say with Pascal Titan X, they run cool on air and even under load never get to a point where the performance takes a hit. They come close, but never trip the threshold like Titan Z would.

if You tweak fan curves a bit, You can avoid thermal throttling (if airflow in Your build is plenty enough).
in my case I put them under water to avoid noise and any high temps.

Z was dual chip card, that cooler never stood a chance to cool both of them for continuous loads. TitanX/1080ti with blower coolers was great though as those coolers were over engineered and capable to handle higher TDPs than what electronics dumped on them.

LOL...I remember one of my first posts back in the day was asking if one had $3,000, would you buy 3 Titan X's ($1k) or 2 Titan Z's ($1500).
You gave good advice by saying 3 Titan X's....but I didn't listen....

Thanks again Tom, hope all is well!
