RX 460 vs RX 470 Reference heat

[boxofawesome]

So as far as im aware there isnt a blower version of the RX 460 avaliable, Im wondering which is going to put more heat into my system

A RX 460 with open air cooler, exhausts into case, lower tdp
Or RX 470 with blower, exhausts out of case, higher tdp

Im kind of limited by my pc case in terms of cooling options, so i dont really want to have to buy a more expensive blower card if its only going to make a negligible difference

case has 1 80mm intake on the side panel, and 1 80mm exhaust. Psu is at the top of the case with the fan extracting from the inside

Thanks

An open air cooler will generate more heat inside the case, meanwhile blower type GPU will take air from the inside of the case and throw the heat out of the case.

An open-air cooler will run cooler and will achieve ~5% better performance when compared to a reference blower style GPU cooling solution and the system will be hotter inside, but if you think your system's cooling capabilities are limited, go for blower style cooling type GPU.

Thanks for the reply

so even though the 460 has a much lower tdp, it will put more heat into the case?
Surely the blower isnt 100% efficient at removing all the heat it produces

I would approach this from another angle. The 460 and 470 are two completely differents level of GPU, if you need a 470 then a 460 isn't really an option in any case(no pun intended). It's also trivial to add an additional fan inside the case to direct airflow through problem areas. This is unless your case is really small and even a small fan won't fit inside. That's small enough that I think I'd want a card with a blower fan.

Agreed. These 2 cards are from 2 different levels. All i said there was about cooling types. Theoretically, a blower style cooler should blow out most of the heat to the outside (100% is impossible).

RX 470 will deliver much better performance and, possibly, better temperatures inside the case than 460 because if the cooling type.
