4 out of 5 eggsa monster

Pros: its big and plenty of airflow. probably one of the best short of liquid cooling. blue is my favorite color. and its not loud. even with 3 fans

Cons: its BIG. if you want 4 sticks of ram dont buy it. i had to use both channels A and B of my ran just so i can fit the cooler in the case. but no big worries. it is what it is. it wont get 5 eggs because i cant use the other 2 A and B slots of my ram. im useing the ASUS sabertooth 990 MB

Other Thoughts: i suggest buying a smaller cooler. zalman will always have a place in my case and they did a good job at explaining how big it was in the description. but i didint realize how big it was untill i saw the box. and it was nearly the size of my head. LITERALLY. like a 7 year olds head. its huge. its as tall at a 12FL oz glass bear bottle. pretend your PSU is your cpu heat sink. THAT BIG.

4 out of 5 eggsIt's good, but...

Pros: It worked well to keep the CPU cool.

Cons: I have a very large case, ATX super tower, and it did not fit in my case. I ended up returning it because I could not close my case.

Other Thoughts: If you do buy this item, make sure you measure your case and have the room for it.

5 out of 5 eggsHuge, Cold, Silent

Pros: -Keeps my OCed 4930k @ 4.8 GHz at a cool 65C at full load on 12 threads on Wprime/OCCT
-Very, very quiet with max fan speed
-For daily use and gaming, the fans never kick in on my custom cooling profile (fans remains off until the cpu hits 50C).
-Plays Skyrim/GTAIV with fans off (temps never go past 45C)

Cons: -Huge, blocks 2 of my ram slots an my only other PCIE 3.0 16x slot on an ASUS Rampage IV Black Edition, so to do a proper crossfire config I'd have to get water cooling or a less manly air cooler.
-Had to install it on motherboard outside of the case then place it into the case due to it's sheer size
-Installation is sort of tricky for LGA 2011 chipsets, and almost impossible without taking you mobo out of the case

Other Thoughts: The bottom plate where the heatsink comes into contact with the CPU isn't completely flat and has small grooves as the heatpipes are in direct contact with the CPU and thus requires slightly more thermal paste in order to get proper coverage (thermal paste credit card technique is an absolute must for this heatsink)

5 out of 5 eggsOhMyGosh!!!

Pros: - OhMyGosh! This thing is HUGE! As others have said, make sure you have room. I had to remove on case fan to make room, but it was WELL worth it.
- Getting about 15C LESS CPU temp over previous cooler. This thing ROCKS!
- PLAN where this thing will go & know what you're getting into, BEFORE ordering OR installing. This cooler is a MAJOR addition to your case.
- Previous normal CPU temps (on over-clocked AMD Phenom II CPU) ran about 42C idel and 55-60 during tasking from flight sim game & add-ons. Now, I am sitting here watching a fully tasked CPU running at 42C. What a difference! Idel temps are around 30-32 now, vs. 40-42 before.
- Well worth the investment!

Cons: - Took an afternoon to install. Had to literally take all PCIe and other cards out, as well as remove my MB completely.
- Believe it or not, but the allen wrench for the cooler hold down screws could have been longer! It's pretty dang long now, but could be about an inch or two longer. It was a REAL tight squeeze getting to the screws in a tightly packed case.
- You have to be REAL patient installing this thing. It's not a qucik swap-out as smaller coolers are.

Other Thoughts: - Directions could have been a bit clearer. Be sure to read over them a few times before tackling the install.
- As mentioned, Allen-wrench could have a bit longer reach for tightly fitting boxes.

5 out of 5 eggs

Pros: Most importantly: it cools my FX 8320 extremely well.

Exceeded expectations for quiet noise levels.

It has a very exciting look- the three large glowing fans look great from the side. (Do a goolge img search)

Cons: It's HUGE, but you should know this and do your research before you buy it. The larger size also ends up being a plus, since it helps with performance.

It's not what I would call easy to install. I didn't have any problems here, but it's definitely more involved than a smaller HSF that would clip straight onto the socket. You must removed your mobo from the case since you have to access the backside to bolt on a new bracket for stability. It's not hard, it's just involved. The instructions are fine.

Other Thoughts: It just *barely* fit in my case, but I had no problems fitting all my components with decent cable management. I'n VERY happy with performance, looks, and noise levels. It's essentially silent.

4 out of 5 eggsQuiet Cooling

Pros: Does a great job at cooling and very quiet. I've never heard the fans kick on to full speed during intense gaming. Intended it to be a temporary solution until I could go with water cooling but it performs so well I never needed to.

Cons: Very large and covers up memory and 1st PCI-E slot on my ASUS Rampage IV Extreme board.

Other Thoughts: The triple fan is nice, but wish it wasn't as wide and higher off of the board to clear memory with heat sinks on.

5 out of 5 eggsLarge but good

Pros: Works really well. It keeps my FX-8120 OC'ed to 3.8 GHZ under 40 degrees at idle and under 48 under heavy load. Unless I'm gaming, it usually stays around 40-42 degrees Celsius.

Cons: None really, just read carefully before buying to make sure it's right for your build.

Other Thoughts: Here are some things to be aware of. It's freaking huge, be sure you have room before buying. Also, make notes of the direction of your case fans. It's really easy to let them cause turbulence against the air flow from this cooler. I reversed the direction of two of my case fans and dropped my cpu temps by around 5 degrees celcius. I also tested it with prime 95 and let it run for about 2 hours. My cpu never got above 50 and the max temp is 52. That is pretty amazing. I think the only way to get better cooling than this is with a custom liquid cooling setup.

5 out of 5 eggsHuge, but good.

Pros: Silent with great cooking

Cons: HUGE, know your board as you must use low profile ram, and as in my case, also lose your first PCI-E x16 slot

4 out of 5 eggsVery quiet

Pros: Super quiet. I can barely hear this fan.

Cons: Started rattling after a few months and had to send it back. It took over 3 weeks to get a replacement but was under warranty.

It's huge and blocks my RAM slots on my motherboard.

5 out of 5 eggsWorks as it Should

Pros: -Brought my i7 3820 from 60c under load to 40c @4.3
-Came with "Super Thermal Grease".......used Arctic Silver
-Fits very snug and bracket don't feel near as cheap as some

Cons: Makes a terrible cup of Coffee

Other Thoughts: Build

If you have the same build you can fit 6 sticks which wasn't a big deal to me but some just feel the need to complain.....even though the dimensions are on the product page
