GTX 460 Shroud

Question! Would there be any improvement in terms of temperature peaks with a GTX 460's shroud OFF? If someone could provide tests and results, that would be awesome! This idea of mine sparked when I saw the MSI Cyclone cooler, it's not that much different in design, except for some customizations and improvements to the reference cooler.

Idk. It's just a thought, with that shroud keeping warm air locked within itself.




It would be most appreciated if my request is respected. Thanks!

PS. It obviously wouldn't be applicable to those of you who own a Palit/Gainward 460! The fan's attached to the shroud, so the sink wont work if you dismantle it.

No. I'm asking you guys if removing the shroud off a 460 would induce better airflow. I'm asking someone with a stock 460 to run some tests. I dont own a 460, I'm just curious about this certain concept. :3

i will in a hour, have to finish folding.

Aint that a sticky. No difference judging from your setup! I can even see a tad higher temp with the shroud off than on! Even your fan profile had to compensate!

Thanks for testing that out for me! I guess there was no point to my thought, though, there could be some variables that can be cited here.

Such as your cooling setup. Do you have any fans blowing into the card's direction? If any, I hope they're filtered and with high CFM. If not, the shroud induces exhaust out the back, somewhat, without it, the warm air gets caught up and under your graphics card instead of out.

Hmm.

Exhaust fan right near the GPU? Hmm. As I can see, the K-58 doesn't come with a provision for a fan on its side panel. Y'know. That might be it. I can see warm air getting trapped right under your card with that setup.

I would assume that without the shroud helping to direct the air out of the case, there is a lot more warm air being exhausted in and around your card. Warmer ambient air, warmer temps.

Also, I think I read (possible in this forum) when looking up the CFM on the GTX 465/470 fan that they have higher air pressure, lower CFM, due to the shroud and it being more efficient in this configuration. Though someone else would need to shed more light on this

That's what I was thinking! His case isnt equipped with a sidepanel spot to attach a fan on! The results could be more definitive if our kind tester would be able to either improve his airflow at the lower portion of his case.

And this is the GTX 460 we're talking about.

I do agree that the reference design from Nvidia on the 465/470/480 are inadequate. The cutout on the PCB does nothing. It would have been more sound to cut through the shroud instead of the PCB! I think that would provide better airflow if anything.

Old thread but hey, i'll be a necro.

I pulled the shroud off of mine last night just because i like the look of the fins and was hoping to reduce the noise.. Mine is the EVGA SC with a little more clock than it comes with. I installed using Antec Formula 6 and put it back to work folding. Its 1C lower than it was with the shroud on. I always stayed at 63C while folding and now after running for over 12 hours folding it is sitting at 62C. The biggest benefit is the massive sound reduction. At full tilt i can certainly hear it but its not annoying like it was before. I just screwed the fan onto the heatsink and its been doing great. This is on a corsair 600T with a 200mm front intake, dual 120's on the top pushing through an H100 and then a 120 exhaust in the rear.
