Heat rises.

Heat does not just rise. It's an energy that can transfer in any direction. Hot air rises but that is because it's less dense then cold air and it rises slowly in a PC case sitting in a room temp room. Stick a fan into hot air and will go in any direction you want it to.

@EarthDog
unless your running a dedicated gpu, and temps throttle the boost (NOT talking about thermal throttling at high temps),
as for last few gens Nv starts that at 54*C.

@bug
until recent i never cared about front fans, and as long as your not using ultra low rpm fans, it wont matter.
especially with use of pressure (vs airflow) fans on heat sink/radiator.

He is, if talking about a passive cooled rig and heat meaning "hot air".
But only when gases and gravity are involved. Go to space and its not rising (making your statement incorrect as well).

@EarthDog
a couple of degrees less (top mounted exhausting rad) can make a huge impact on boost clocks.

@DeathtoGnomes
wasnt sure if you knew, since you stated heat rises (not hot air).

like earthdog has stated, a 2-3C difference in temps that are within operable spec won't increase/decrease FPS, open up new levels in games, lower your tax bill...it's not like adding RGB to your case ;)

@EarthDog dirtyferret

how about a water cooled 2080 (non S) providing better fps than an air cooled ti?
sure with lower end cards its usually a non issue, but seeing i get sustained boost clocks that are 30-100 Mhz higher than most air cooled cards can do as peak max for 1s.
e.g. 2-3*C can mean 55*C (and boost clocks start to drop) vs 53*C.

so 53C is an operable temp spec for boost clocks and 55c is not? (if so see my statement above) :)

*edit: out of curiosity which game? At some point the extra memory, ROP units, texture units., etc., on the ti come into play regardless of boost clock on the 2080.

yup, temp related throttling comes on past 54*C, which i could easily verify.
game doesnt matter, temps do, so any load that gets the card past 54*C (easy on an air card) will lower boost.

didnt heat the room for 10 h, card stayed below 54 for the whole benchmark,
as soon as the rad was soaked and temp went above 54* (i run fan on low rpm), boost clock starts dropping by 15 Mhz.
boost clocks keep lowering, until you reach temp throttling, then core clock goes down.

in short, yes a couple degrees can make a difference.
and when i see how many ppl might just glance over posts/answers, reading: .. doesnt matter...
only to "cripple" performance because their hw/setup is slightly different.

As others said, not a big difference between top/front, except with bigger gpus.
I overall prefer to mount it to the top of case, as less than a handful have side (exhausting) rad mounts, and front mounting usually increases overall temps on other stuff, while top only affects cpu temp a bit.

Honestly, if its that big of an issue to you then keep them at test #1

lol, I'd love to see the OPs air cooled card sit at those temps....ain't going to happen.. and if it drops a couple of boost bins due to temps, like running 74C versus 71C, only a benchmark would pick it up. What are the bins...7 MHz? Come on now.

in short, yes a couple degrees can make a difference.
and when i see how many ppl might just glance over posts/answers, reading: .. doesnt matter...
only to "cripple" performance because their hw/setup is slightly different.
cripple? Please stop being dramatic. Though each chassis is different, check out his video... about 9 mins in should do...

I found this on YouTube (a video by bitwit). What do you guys think?

I think you should enjoy your pc...lol. each case is different man... it you can see there the GPU conversation is much ado over nothing..

Should i try furmark to see gpu temps or theres any soft that tortures both gpu and cpu at the same time? Maybe unigine? Thanks.

You should stop asking questions and just enjoy that pc... :p

Being serious, dont run furmark. If you want to unrealistically load your PC and continue testing for whatever reason, run prime and unigine for 30 mins, sure. But again, my dude, you are living in the minutia (seeing all the threads you've started) get your head above water and enjoy it. :)

Yes, playing video games. In fact if that's the most demanding thing you plan to do with your PC then it will also be your best real world benchmark. You may like benching your PC through video games so much you may give up on your temperature crusade and start enjoying your PC...

@EarthDog
Never said his card will, but maybe its easier to say it like this: passing 54*C cards will drop boost, the higher the temp, the lower the clocks.
So it's not looking at 71 vs 74, im looking at 54 vs anything above that.
The lower the temp i can get, the better, and that incl mounting the cpu rad on the top.
