Looking at building a custom case from wood for an old PC for a project and was thinking about airflow etc.

Would there be any issue with having a dedicated airflow duct for the video card ? So instead of the case being open internally, there would be a dedicated fan pushing fresh air through a duct that the video card is in. Obviously it wont be 100% sealed due to the motherboard etc

Something along lines of this

The video card Ive got is a 6970HD which has a massive heatsink and a fan.

Ideas/comments :)

Just have a filter for dust and it should be good, maybe another fan after the card to pull the hot air as well.

Is it a blower card?

i honestly dont see the point, just suck in from the front/bottom and vent from the rear/top, that way everything in the case keeps cool

Its this one. The plastic cover is a bit shot due to rough ownership previously to will be leaving it off.

Ok, so its a blower card which exhausts air out the back of the card. Yes your idea will work and no need for an exhaust fan as the card will do that but how do you intend on feeding fresh air throughout the rest of the case to the CPU and what cooling are you using for that, water or air cooler

Is it worth removing the shroud from the heatsink on the card itself? This should get more airflow over the fins?

That could be bad as it will reduce the local air velocity. Easy enough to try each way and measure though.

The shroud is already off as its damaged. Think someone took it off without checking how it was held on to start with ;)

Its 10 years old so cant expect it to be perfect ;)

Will just have couple of other fans to keep rest of the system air cooled.

Is just my old G3258 rig, Im fed up with it sitting in a cardboard box on my desk with a 120mm fan pointing at the video card to keep it cool ;)
