Pros: I have a Sandy Bridge socket 1155 I7 3.4ghz unlocked ASUS mobo Z86 Stock Intel cpu fan until this mod I ran at temps like 38c to 42c - unloaded 64c to 70c - loaded After the install of the H80i 16c to 21c - unloaded 22c to 28c - loaded This thing is a beast. Hoses swivel very thick and pliable. They will not kink. Sound - very quiet; you will notice a little racing when you boot but after that it drops down super quiet. Much less noise then the sock Intel cpu fan. Installation - not to bad at all. The sliding adapter pins for the back plane are a bit too loose for me but I was able to get that attached easy enough. NOTE: The plastic piece on the backing plane for intel chipsets you leave on..gives the sliding pins some resistance. Note: one of the exploded views indicates 8 washers only 4 provided if you have 4 paper ones I would use those on the inside fan as well. Software - not included; You can download the monitoring software suite from Corsair "free". Firmware - an update can be downloaded from corsair; applied using the previously mentioned software. Overall "What was I thinking should have done this a long time ago!"

Cons: Instructions a bit lacking. I was going to drop it to a 4 out of 5 eggs but its just so good. Do not put the second cooling fan until you have effectively attached the Y power split-er for your two fans in. I watched a video provided by Corsair and it was pretty straight forward.

Overall Review: Watch the install videos online from Corsair or some of the guides on youtube. If you're case has back plane access "other side of the case" you do not have to take everything off your mother board to install. Firmware update available on Corsairs site Software for monitoring not included you download that from the corsair site as well.

Pros: Decent sound. Very comfortable.

Cons: I have had a set for a year. All the headset screws fell out. The mixamp stopped working. The absolute worst customer service on the planet. I loved the comfort so I went to buy another set. The 10% discount for previous ownership has since been dropped for repeat customers. So I contacted them. They agreed and said will give you a 10% discount manually through the system after you purchase. I did and after I inquired about my discount they said "we no longer offer that". So the lied to my face. I contacted customer service and its been 2 and half weeks of me sending receipts. Them saying "never got it" etc. Two sentence responses for over 2 weeks now. If you try to call them ..they give you a number and don't get back to you. DO NOT BUY from Asto gaming. They are con artists. I have copies of all my emails to prove to anyone i'm not making this up.

Overall Review: This company is extremely shady. The price is way way to much for what you get. If you are fine with just buying them and never needing any support they may be ok for you.

Pros: none that i can see..it will not boot!

Cons: new mobo new cpu new case..all new. will not post. simply cycles for a second then off for 5 sec..then on for 1 second.

Overall Review: I really would shy away from ASrock in general. There customer service is horrid and the documentation is hidous. If you buy this board beware you are on your own. I would recommend Gigabyte, Asus or XFX ASRock is simply not in the same class.

Pros: It was pretty snapy with decent frame rates in wow 50.

Cons: Died on me...I get 8 to 9FPS now in WOW. I tried everything. The card just died on me. Upgrading to a 7800GT. Did not ship with a power cord either.

Overall Review: I'm sure I just got a bad one. I put it on my new ASUS SLI Premium board.
