I see. Truly agree with you that it looks good, kinda figured it was only for aesthetic purposes. Wasn't planning to install the middle fan as it would obstruct the sound card from being installed so I guess he law mower won't be that loud at least. Thanks for your response. Seems like its both a gimmick and a function. I'll wait for more responses before deciding on the Hero, though I very much I would like the Formula since it too has the armor with a different name but sadly, it is out of my budget. Thanks for your response. EDIT: @Freaky_spider, Well, looks like I'm leaning towards the Hero now. Looks like the Thermal Armor is only useful for protection against dust and best from the graphics card.
