Pros: Great quality! I wasn't expecting much but I was surprised when I got these. Fits really nicely on multiple kinds of 120mm fans. I thought these were silver/metal colored but they're actually chromish black.. which is even better! Don't really write reviews that often but I was very satisfied with APEVIA 120mm fan grill. I would definately buy them again.

Cons: No cons.

Pros: - High quality, exactly what you'd expect from Noctua - High performance, comparable to AIOs with 240mm radiator - Quiet - Easy installation - Very user friendly fan clips - superior compatibility Vs. NH-D15 - It will never leak, it will never wear out

Cons: - Like every other high-end air coolers, it is bulky - Only one bundle fan

Overall Review: Though it is highly subjective, if you do not like how the way Noctua fans and heatsinks are designed, you can always check out Noctua chromax line up. I bought 2 (one black, one white) Chromax heatsink covers to match my build's color scheme. The product itself is great but what's even more great is their customer service. They will send you extra fan clips if you ever lose them or need extra pairs for additional fans.

Pros: 1. IPC improvement 10%+ Vs. Ivy bridge 15%+ Vs. Sandy 25%~30%+ Vs. Nehalem Lynnfield/bloomfield. (Nearly 2x L1 cache performance, AVX2 and other new instructions, noticeably higher gflops even with Hyperthreading on due to improved multicore performance) 2. Memory controller improved SOOO much Vs. previous generations. DDR3 rams overclocks WAY HIGHER. My favorite 1866 Dominator platinum dual kit does 2170mhz on Nehalem platform p55 2300~2400mhz on Ivy bridge platform z77 on Haswell it goes up to 2666mhz 11cl !!!!. stable tested using TM5 and prime avx large test. z87 Upgraded memory controller is probably the best part of Haswell overclocking. 3. Added feature on z87 boards, 6 Native sata3 ports, faster 4k QD32 read/write speed VS older Ivy bridge platform. 4. Better integrated graphics. ehh

Cons: 1. Gets hot going beyong 1.3v @4.5GHz, I mean really hot almost as hot as the Ivy bridge or hotter. So deliding might be very useful just like Ivy. 2. IPC improvement isn't that great considering the fact that this is a tock generation.

Overall Review: It's a quite of a big jump even from a Sandy bridge. Cinebench 10.5R Haswell i7 4770k @4.6GHz = 10.16 Ivy bridge i7 3770k @5.0GHz = 10.12 about 10% on overall applications. Even from ivy bridge, if you are a benchmark + overclock lover, I'd say go for it.

Pros: has very powerful over clocking ability, 2000mhz and more my 4th ram from G.skill, all of them were capable of High over clocking above 2000mhz, 9CL usually 9-10-10-24 depending on the motherboard guaranteed above 1600mhz 8gb for $40 is just amazing i have full bank set up ( all ram slots filled) all G.Skill, still was not hard at all to stablize my system

Cons: Ram cooler is kind of big, might want to see if it might have problem with your CPU cooler. you can always take it off but very slight loss in performance (cooling)

Overall Review: first review on new egg, but seriously, they look cool. Try overlocking over 2000mhz and more, because these guys can handle them with 1.65 DRAM voltage, and reasonable ram timing settings.
