Case airflow/cooling question

in reality no, the heat produced by this gpu goes down, it is very close to the bottom, so push that hot air to somewhere on this small case, is a no go thnks to the width of the gpu

remove the hard disk bay and leave a empty space could let cold and hot air flow in multiple directions this way but if there is not a big fan there doing any cold air intake, well, no cold air will flow there to push more hot air away, so all the pc will work hot all the time and the rear fan will do the best it can pulling hot air out

is not a ideal situation but worse situations have been seen and i have used pcs like that in the past, a nice room heater is what it is :D

if you can put the hard disk on other place, that is great, if you can put...

there is no form of airflow there, the hard disk blocks any cold air coming form the front of the case, if any enters that way

the card will overheat and when it does that, it will throttle down speeds and make fans speed as fast as possible to keep temperatures under 90°c

play a couple hours and monitor gpu core speeds, temps of gpu

use msi afterburner with rivatuner to know how bad it does

that case is not meant for such big gpu, it would be better to get a blower style gpu for that case but you already have that one

perhaps at least put a big fan in the front and move the hard disk to the lower bay to improve at least a bit the airflow there?

It's as I feared then,

I do have the option of removing that lower HDD cage and shoving the drive elsewhere. Do you think that'll solve the issue?

if you can put the hard disk on other place, that is great, if you can put another fan in the fornt of the case if there is none, that is great too

with the gpu itself you can't do anything, the size of the case doesn't help here

is the psu on the top of the case right? the fan up there will help move hot ir out but will make the psu work hotter

all you can do is improve airflow by adding fans pushing cold air in and well, play alot to see how bad it gets :D

Well that sucks. I can't really do anything about the placement of that PCIe x16 slot. Are you sure it'll affect cooling THAT much? From youtube videos I've seen, people have fitted a 960 in the same place as me and it has appeared to work fine, like this one - https://www.youtube.com/watch?v=23i5aZSYkCs

The chap in the vid did use a slightly different model of optiplex and the mini variant of the 960 but it's still in the same slot.

I can stick a front intake fan into my PC, boot it up and see what happens if you like but I dunno. Lemme know what you think

it will work fine but the gpu eventually will throtle and the entire case will feel warm, as a room heater

not the ideal situation but it will work

the fan you mention is a welcome modification

but where are you going to put the hard disk?

There's a space free where the floppy disk drive would normally be. When I get chance I'll set this rig up and report back if it works or not, I'll also give ya some temps

UPDATE: The PC works and works well. The GPU is at 30 degrees Celsius idle. (without the fans turned on!) when the fans are on it's about 23 degrees. Under load it's maximum temp was 60 degrees. GTA V runs at a near constant 60FPS with the GPU at about 40 degrees. Also, the GPU isn't downclocking itself and the clock speed is what is supposed to be
