I can't speak for the others but I see no need to shoot you. I only recently finished modding my 650D
You can get a nibbler tool like this for $12. It would be tedious as all get out but you can make a hole that isn't too rough with it, then clean it up with a half round file. You can either drill a starting hole for it or use a pair of dikes (wire cutters) to gnaw out a starting hole.
While removing the punched grill in the front of the case itself will reduce noise noticeably, I would also suggest replacing the stock fan with a quieter one that has more air flow, such as the Cooler Master Megaflow.
Thanks for the reply mate.
To be completely honest with you, I would not want to physically cut the grill (don't have the skills, tools or the patience to perform that lol), I'd rather go the rubber washer route.
BTW, I already replaced the stock cooler with a MegaFlow 200mm (see picture).
I know, I'm replying to older posts. But one other option to quiet things down is to use a fan controller.
I'm using Lamptron's FC5v2 (now replaced by the FC5v3). Its black anodized finish matches perfectly with the 650D, and it can show voltages and fan RPMs. You can also set the LED color to match your fans.
LEVIATHAN got two start-of-year gifts; an ASUS STRIX 980, and a Seasonic 1000w platinum (I found a half-off liquidation deal there that let me give my X750 Gold to the SO's system). Even though it may not be easily available, I still think the 650D was/is one of Corsair's best endeavors.
I will moddified my Obsidian 650D. I think no one done something like that. Exterior will be same, but Optical Bay will be removed and 360mm radiator will be in hole in vertical position near motherboard tray.
That will give him completely different look. Case will be more spacy and radiator options will be far better. Removing Hot Swap Bay for HDD on top will give opportunity to 650D hole 360+360mm radiator.
Only trick would be how to resolve HDD problem. I need place for 3.25" HDD and one CORSAIR Mount for Dual SSD.
There is and other option, cutting Optical Bay and install 240mm radiator on front.
For that I would need one Coolemaster Master Case Radiator Mount.
This is plan... only will be used soft tubes until NVIDIA Volta arrive. In mean time I will cool only CPU RVE10 and VRM with Monoblock.
Without Optical Bay and HDD Cages 650D is something completely different. 200mm fan will not be used at all.
I only hope Dremel 4000 will be able to drill aluminum rivets on case with 1/8" drill bit from 628 set.
I do all of these only because I can't find Lian-Li PC-O11 near me, on Western Balkan and East Europe no Lian-Li at all and Caselabs BH8 is still not available in Europe.
