    Not really, how much do you know about fluid dynamics? Without a high static pressure created by large fan blades and a shroud, the resistance created by the heatsink would cause the air to be diverted away, I.E. towards the gapping open area. Let me photoshop your pic and show you what I mean, gimme 5 minutes.

    You can tell by all the dust having been pushed onto the side of the left copper fins and by the fact I lack any heat issues, that the heatsink works. :P

    I'm not saying it doesn't work, it's just inefficient as hell.

    Without a shroud the airflow wants to find the path of least resistance, a heat sink has resistance, the back pressure caused by this would cause the vast majority of the air to be flung outward by the fan blades, see below. The red arrows are airflow btw.



    With a shroud the air is channeled where it needs to go, any back pressure caused by the heat sink would be overcome simply because the air has nowhere else to go, which would in turn cause the fan to push harder. That's why static pressure fans have thicker blades and less air gap between them. Image below is merely a dramatization.



    Hope the visual helps.

    You have to take a few things into consideration when looking at that particular heatsink:
    • RPM and static pressure of the fan.
    • The shape of the rotary blades.
    • The fact that the fan is smaller than the heatsink.
    • The shape of the heatsink.

    The heatsink shape makes air "trapped" within the confound space of the heatsink. It partially engulfs and creates a pocket around the fan that pushes air through it's center (think of a funnel). At the same time the rotary blades are shaped to twist the air in a tunnel, creating a whirl.

    I made pictures for you:




    From a physics standpoint it makes perfect sense. Some air will escape around the edges, but not any significant amount. A shroud would most likely help overall, but not make that much of a difference in the long run.

    Inefficient? Well, that depends on what you compare it to. It's definitely a good cooler based on the fact that it can dissipate a fairly large amount of heat, but compared to a box-heatsink and a shrouded fan it's less efficient per cubic centimeter; size (most likely).

    Made a small album of my gaming setup, it really shows that the lens of my phone's camera is knackered.

    Clickety!

    Well I guess the descriptions in the album are lacking in detail, here's what's going on:
    CPU: Intel Core i7 920 @ 3.2GHz
    Mobo: MSI X58 Platinum (Crossfire version, D'oh!)
    DDR: G.Skill 3*4Gb kit
    HDD: Western Digital Caviar Black 1TB
    SSD: OCZ Agility 3 120Gb
    GPU: Gigabyte 660 Ti WindForce SuperClocked
    Case: Antec 300
    PSU: Zalman 850W (ZM850-HP)
    Monitors: Samsung 245B (24", 1920*1200) and Acer AL 1951 (19", 1280*1024)
    TV: Some Samsung from ~2008 (46", 1920*1080)
    KB: Original Logitech G15, seen a LOT of use and it shows, still love it.
    Mouse: Razer DeathAdder I bought from a friend last week.
    Audio: HDMI goes to my Yamaha RX-V765, which is connected to my locally made 5.1 speaker set with AudioPro SubFocus 10" sub and beyerdynamic 770 Pro headphones.

    Laptop is a Samsung R530. It's got i3-330M, 310M, 4gigs of ram and a 500Gb HDD. Display size is 15.6" and resolution 1366*768. Battery life is 404 not found.

    That makes more sense, I wasn't aware that heat sink was domed in like that to account for back pressure.

    Adam Audio monitors are the speakers of my dreams. Got to hear the A7Xs at my local Sam Ash a while back and good lord, just absolutely beautiful! Plus they are so damn aesthetically pleasing to the eye and really accent dark surroundings. Gahhhhh

    I tried the A7X (the size difference is huge!) but my gaming room is way to small for the A7X - I had more bass outside of the room than inside.

    Rofl! I wish I had the funds to sink, but for now my Samson MediaONE 3A studio monitors are sufficing quite well.

    Are you planning to get the sub to go with your monitors?

    The +dB bass setting provides sufficient enough bass for me. :-)

    Hey Guys I am sorta new but I love computers so here is my setup

    CPU - Intel 3770k

    GPU - EVGA 690 GTX

    SSD - Samsung 840 Pro 512GB

    HDD - WD Caviar Black 2TB

    PSU - OCZ ZX Series 850W

    RAM - Corsair Vengeance LP 32GB

    MB - ASRock Z77 OC Formula

    Cpu Cooler - TPC 812

    Case - Cosmos S II

    Thermal Compound - Innovations Cooling - IC Diamond

    Additional Fans - BitFenix Spectre Pro LED White 200mm ( Front of case )

    Additional Fans - XIGMATEK eXTREME SILENT ( Top and side case fans )

    Additional Fans - Xigmatek AOS (Aeronautical Oil System Bearing) XAF-F1255 ( Push/Pull Configuration )

    I still have some planning to upgrade it soon with another 840 pro and the new Titan card when it comes out. I would post links to it all on newegg but Mmo-champ said no lol but you can find it yourself if you are really that interested.

    Pictures Link

    newegg links are someone pointless as most of us know where to buy those parts, and not everybody can use newegg, instead post pictures of your computer
