I'm a noob here and I'm not sure which of 120mm/140mm/200mm might suit in the case.
So, I need a GOOD high speed cooler fan which suits BOTH the Coolermaster HAF 922 and the iball case mentioned. High speed fans preferred, and of coolermaster ones or ones that can be bought from ebay/flipkart since I'm from India
i assume your after case fans... unfortunately it doesn't say on the "iball" spec sheet what it can take, but my personal favorite in the coolermaster range @ 120mm would be the blademaster fans. very quiet @ low speed, shift large amounts of air @ high speed. good for cases & heatsinks. http://www.coolermaster.com/product.php?product_id=6622
no idea how much they retail for in india, but very reasonable over here in the uk @ ~£7 each
+1 with the noctuas. they're a fair bit more than the coolermasters, but may be worth it to you for the quiet performance & long warranty. The blademasters served me well in a couple builds beforehand but since i've switched i appreciate having both top notch cooling & silence - superb for listening to music while i'm computing.
Thanks for the suggestions. I'll look onto it. I'm basically looking for CASE FANS with OPTIMUM cooling, price is not the concern. It just needs to fit the 2 cases I mentioned and possibly mention of any famous ones that are available in USA/UK too since I may try in online retailers(ebay..). All the famous ones are available to India from ebay.com. Also, noise is not of a big concern too, unless its really TOO much
