Pros: - Kept my i5 4590 temps low (not a surprise, as stock was almost as good)
- Never had a problem with it after a few months
- Even though it's clunky, it looks nice.

Cons: - None

Other Thoughts: Make sure it fits in your case

Pros: This cooler just works. Put it inside new 5830k build and at stock 3.3 this cooler keeps it in the 30s idle and low 40s under load. After oc to 4.0 cpu idles at 38 and under full load maxes at 58! this with ambient temps near the 30s in Texas. Assembly and mounting was the easiest from any of my previous air coolers and mounting of a 2nd fan was a must I wish I would have tried it stock but it's so easy to clip the 2nd one on and I had a fan I figured why not.

Cons: not really any big ones. have to be sure the cross bracket is centered in the base of the block or it might move around when you go to synch it down but lime I said this was 2min for me to realize what was going on and install was still astronomically easier then my last arctic cooler.

Other Thoughts: what else is there to say. catch this on sale for under 20 bucks or even 15 and it's a no brainer.

Pros: Lightweight, effective CPU cooling. Allows any 120mm fan. Impressive for the price.

Cons: Very poor quality fan. Don't expect it to last forever. What did you expect? It was good of them to include a fan at this price. I'm happy.
Only fits inside a full width computer case. Low-pro is no-go.

Other Thoughts: Read the directions, seriously. Be careful, and enjoy. It's much better than most stock cooling solutions.

Pros: + Not outrageously gigantic.
+ Quiet and efficient.
+ Relatively inexpensive.

Cons: - Can be tricky to mount.

Other Thoughts: I have the Hyper T4 installed on an i5-6600K that is overclocked to 4.4ghz at 1.36v. My idle temps hover between 27c - 31c and under heavy load with Prime95 I've never seen higher than 73c. I am running this unit in a push/pull dual fan config in a case with very good airflow.

It's obviously important to apply your thermal paste correctly, and I believe many people have a poor technique (even long time PC builders) due to the great many poor tutorials online and elsewhere.

The "pea-size dab in the center of the CPU, and then apply the heatsink" methodology is risky. Often this works out fine, but it can often result in uneven distribution of thermal paste, and/or air bubbles that prevent a good thermal transfer.

The "correct" technique is to squirt a ball of thermal paste a bit smaller than a pea on to the center of the CPU, and then with a gloved (or clean and dry) finger, smooth the ball of thermal paste into a very thin, even layer across the entire top surface of the CPU. When finished, there should be a uniform layer of thermal paste with no obvious thin or thick spots. After ensuring a consistent, thin, uniform layer is present, apply your heatsink as usual while trying to minimize any unnecessary twisting, sliding or lifting once the heatsink base has made contact with the CPU.

It's important that the layer of thermal paste be very thin. The paste is only meant to account for any imperfections in the flat surface of the CPU and the heatsink base. Any excess paste only serves to hinder efficient thermal transfer.

Pros: I have a ASUS P8Z77-V LK, with a Intel I5 3470 inside, Will only mount up or down because of Motherboard heat sink. Had to take the heat spreader off one of my Vengence ram. Cools good but the fan that came with it is rattling. Keeps my CPU at 33 C idle/ 61C under full load. Use Artic Silver 5, not the ketchup pack thermal grease they sent with it.

Cons: Fan is bad out of box.
Price is a little too high considering having to buy another fan

Other Thoughts: This is my first time buying a Cooler Master brand, and I have concerns about their Quality Control. This fan shouldn't have made it pass. I bought this over cheaper brands because I thought it would be better quality, was a real let done when I started my PC and heard this annoying rattle. I would feel reserved to recommend Cooler Master products to a friend. May try to contact Cooler Master, I'll update after I talk to them, if I can get a human there!

Pros: Super-Easy install on an AM3+ CPU socket. Reminded me of the old AMD Athlon CPU coolers of decades ago. I don't think any AM3+ Cooler install could have been easier. Came with plenty of hardware for other sockets like Intel. Saved those parts in a labeled and zippered sandwich bag.

Cons: No Cons. None. This is just what I needed for an AMD AM3+ FX-4350 CPU. Everything I needed was provided. No Cons whatsoever. Very Pleased!

Other Thoughts: I did install a 2nd Cooler Master 120mm PWM Fan with a 4-pins PWM tail plugged into the Asus AM3+ Motherboard "CPU OPT" port. Everything that was required for the 2nd fan came with the cooler. I already had the second CM 120mm PWM fan on hand. This cooler went into a Blue-themed Asus AM3+ motherboard. FX-4350 CPU and then 2x 8GB sticks of Crucial DDR3-1600 RAM. We used Arctic brand MX-2 heatsink grease, 2x 4-grams syringes. NOTE: A Word to the Wise !! - Install the RAM *BEFORE* you install the CPU cooler as clearance to install RAM after the CPU Cooler is mounted was a bit tight. Installing the 2nd set of two RAM sticks would require pulling the cooler off of the CPU, then cleaning both the cooler and the top of the CPU, and then using new heatsink grease before re-mounting the cooler. But this is not unusual and it is NOT a Con for me. However it may be a Con for you. YMMV. I was able to install the cooler without having to access the underside of the motherboard. Just one simple locking clamp. Easy-Peasy. The motherboard remained mounted onto the motherboard plate from the case during the whole install procedure. This set of new parts - FX-4350 CPU, CM Cooler, 2x CM Fans, grease, Asus Motherboard, and Crucial RAM - breathed new life into a client's Win_7 PC. I could not find another heatsink fan with 4 direct-contact heatpipes and up to two 120mm PWM fans for a lower price. We payed about $25 for the cooler on or about 2-26-2016. Best Bang for the Buck !! Very Pleased Indeed !!

Pros: cpu never gets hot

Cons: large heat pipes get in the way of the memory

Other Thoughts: would like to change the mounting to mount the fan facing the rear

Pros: Easy to install.
Keeps it cool.

Cons: Big but it has to be.

Other Thoughts: Had it installed on the computer for several months then bought a H60 and installed it. The computer seemed to run hotter would get idle temps 40c-45c and loaded 60c-shutdown. Tried switching the fan around to no avail used just the top exhaust fans still ran hot tried many ways to get more air flow over the radiator nothing seemed to cool it down so I installed another H60 same result. Went back to the Hyper T4 and I get 25c -27c idle and 45c- 50c under load in an ambient temp of 28c.

Pros: As others have said, cooling performance is about the same as a 212 evo. The pricing is slightly lower, which is likely its best selling point. It's competently executed, and if you've got an AMD motherboard you'll send less time mounting this than you'd expect.

My greatest praise has to be that the cooler is beefy, without being obtrusive. I thought I'd only be able to fit one fan onto my board, given that micro ATX doesn't leave a lot of room for coolers. Surprisingly enough, I fit both fans and still had room to fish the 4-pin power connectors and mounting screws around the board. It's nice to be able to have a big cooler, but still be able to work with the computer.

Cons: The mounting is...not ideal. Put simply, the cooler is held on with a pressure bar, and the bar hold the cooler in place laterally with a single cross-beam. While this does make mounting a simpler affair, you can actually flex the cooler across the surface of a processor (a 1150 in my case). That kind of give on the cooler is something completely new to me, and I can't say it's comforting.

The inexcusable problem with mounting is that you have no flexibility. The bar used to apply pressure to the cooler has to cover the processor, which means you're limited to two directions for cooler airflow. It's just sloppy design work.

The instructions for installation are absolute gibberish. They go to the effort of depicting everything, and even numbering it. All of that effort is then wasted by having the instructions blobbed together, such that it's nearly incomprehensible. I'll admit, if I'd never installed an AMD heatsink I'd really have been frustrated. Thankfully, this is an annoyance rather than a deal breaker.

Finally, the back plate is surprisingly odd. You can slide the threaded segments outward, allowing for up to LGA 2011 sized sockets, but there's nothing holding them in place. It seems silly not to just have them as large threaded screws, for all the rigidity they lend to the system.

Other Thoughts: Would I buy it again? No.

Would I recommend it to people? No.

This is a competently executed product, and it does what it says it does. At the same time, the 212 and 212 Evo are miles better on the mounting hardware feeling solid. You're looking at about a 20% savings with this cooler (when compared to the Evo). You're looking at an expenditure that cannot be justified by performance, aesthetic, or construction. The extra cost, from my perspective, is all in the mounting hardware. I'll gladly spend the extra money, so that I feel like my cooler is solid.

If you're budget can't fit in an extra $5, then this cooler is competent enough. I would highly recommend spending a couple of extra dollars to get something with better mounting design, but the performance is similar to other offerings.

Pros: + Can be up to $15 less expensive than the 212 EVO
+ Smaller (148 mm)
+ 120mm fan

Cons: - Can only be mounted 1 way on AMD motherboards (fan facing up/down)
