Pros: Fit and finish were great on this and they were pretty quick to send the AM4 bracket after it was released (took 4 days to get to the USA Midwest from Taiwan). Cools my 1700 without much of an issue even though I'm not pushing it too hard. Idles somewhere between 32-38 but under Aida64 Stress Test it hits a high of something like 55, which is a nice 7 degrees from my previous Corsair A70 cooler. Fans are quiet, running it with the stock fan + a Cougar fan in the rear.

Cons: Only con I'd say is that for installation, you need a 6" or longer screwdriver. I had one on hand but it was a #2 head which is too big, so I had to postpone my install for a few hours to go to harbor freight to grab a cheap screwdriver.

Overall Review: Definitely recommended. Good cooling performance for the money

Pros: Relatively easy to install(A quick once over of included hardware was all I needed to know how to install it) Keeps my i7 6700K SUPER cool Looks pretty neat Push/Pull configuration easy to set up Includes clips for second fan

Cons: Size needs to be a consideration(Not necessarily a con, but if you have a smaller case than "normal" you may have trouble) Essentially requires a long philips screwdriver(All of my screwdrivers with bits were too large for the hole, I had to use my standard screwdriver)

Overall Review: I would absolutely recommend this for anybody who wants to get seriously good cooling at a ridiculously good price. I would LOVE to see more products from Reeven, and this price point is unbelievable. This is literally the best heat sink at this price point bar none.

Pros: Overclocked CPU stays cool at idle and under load. Price and performance beat other coolers like my Noctua monsters which cost quite a bit more.

Cons: None

Overall Review: Consider this unit and compare reviews with other enthusiest brands.

Pros: - stable OC at stock voltage for Skylake 6700K @ 4.6Ghz - running Prime 95 max heat test temps never exceed 71 C at 75 degree F ambient - running Handbrake transcodes temps never exceed 69 C

Cons: - none; it's big, but you won't get this performance from a dinky heatsink

Overall Review: - would recommend this to everyone - go read the review and performance testing results on HardOCP

Pros: +Easy to install as long as you have a very long screwdriver over 160mm long(not including its handle). +The yellow and black fan looks pretty nice, especially with my Pink and teal RGB lighting. The pink makes the yellow fan look like a blood orange red color and the teal reflects off the top cover and logo. Nice! +The top cover plate which is like some brushed aluminum looks fantatsic. Really, it does. +It is quiet. I can hear my video card fans and Noctua case fans over this thing. +This cooler really looks good. (Oh, did I alreay mention that?) +It performs very very well for its price and size!

Cons: An installation method not requiring a super long screwdriver. Seriously, you better have one. Luckily I already had one from my Cryorig R1 Ultimate cooler.

Overall Review: I replaced my Cryorig R1 Ultimate cooler with this. Yes, you heard that right. The Reeven actually cools better than the R1 Ultimate. I have no idead how that's possible, but my AIDA64 results are below. I'll let the numbers speak for themselves. AIDA64 (15 Minute stress test on CPU, FPU, and Cache) *All temperatures in Centigrade* Cryorig R1 Ultimate: CPU : 64.2 CPU1: 66.4 CPU2: 67.1 CPU3: 65.9 CPU4: 67.3 REEVEN JUSTICE: CPU : 57.2 CPU1: 63.4 CPU2: 64.1 CPU3: 61.8 CPU4: 61.0 If you read this far, just click buy already. You will not regret it. No other cooler on the market cools this well at this price. It's crazy!

Pros: In high ambient temperatures this replacement HS/F runs step for step with the H100 closed loop cooler I was using before, right out of the box. I didn't bother adding a push/pull configuration or get to use the high-grade thermal compound I wanted to because another order didn't come through, but it was no problem.

Cons: This is more of a warning than a con. You definitely need a longer-than-average screwdriver (at least 160mm) for the JUSTICE. A 'tool' is provided that you may be able to get under the heatsink with, but it's not feasible to use with my particular setup.

Pros: -Sturdy build -Quiet -Drops my temps by 20-30 c -Clear instructions -Option to add second fan to cooler

Cons: - Can block the first memory module slot if you have huge RAM heat spreaders. Smaller spreaders like the Gskill ones can be cleared by the fan

Overall Review: - Needs a Phillips screwdriver longer than the standard 4" to install

Pros: It's pretty massive, however, even with RAM with heatspreaders, the memory generally can be installed into their respective sockets without removing the fan. It has good clearance. If you're ram has crazy (and pointlessly) tall spreaders then you might run into an issue, but I doubt it. Keeps the Pentium G3258 at stock clocks ICE COLD, the cooler is literally cold to the touch while the processor is under load, Overclocking the chip is not an issue on Air at all with this beast. Probably getting another 120mm fan from them to install with the provided additional fan clips for a push+pull config. It gets you a degree or more, nothing major, but every degree counts when OCing a chip.

Cons: Nothing that I am aware of. Installation is a bit tedious. The only thing I can think of is that I didn't have a screwdriver with a 160mm length handy to install the retention screws (which wonderfully pass directly through the tall heat sink). I had to use the supplied micro wrench. It took me a while to secure the HS but, who cares. Might be kinda tough for people with big hands (like me). Otherwise, installation was almost stupid simple.
