Pros: Very rectangular shaped heatsink. I like how it has clips for both sides provided (unlike some other brands that work with two fans but only give you one clip and somehow you need to find another clip!). I use the fan resistor and that keeps it much quieter (I am picky with silence so I will mention it is a little louder than my 4 Cougar case fans :) ), and it still maintains the same temp (around 46C no load with FX-8150). It has a very smooth and flat copper bottom ...
Cons: It blocks a RAM slot on a very well RAM spaced motherboard. And yes, I have the shorter side of the heatsink facing the RAM and the longer end facing the back of the case. I expected this when getting a larger heatsink, and AMD RAM runs in dual channel mode only, so I moved both of the RAM sticks to slot 2 and 4 from 1 and 3 and they still function perfectly. I mean, dual sticks come well priced up to 16gb which about the max you really need. unless you are filling al...
Pros: This things a beast at cooling my 955BE at 3.8GHz, keeping my Idle temps around 26-29c and loads have never hit 40c yet even when rendering in Sony Vegas! Temps for when I'm playing games like Crysis/Mass Effect 2/Dragons Age Origins, almost never go past 34c, and this is in an older Aspire X-pider case with 5 80mm case fans so this coolers definitely doing a good job not to mention the paste it comes with seems to also work better then the AS 5 I use to use. All in a...
Cons: only that the back plate can be tricky to get on just right, good thing it comes with 2 double sided sticky tape pads, but other then that it was actually easier to put on then I thought.
Pros: Installed this with Artic Silver 5 on a M48a79xtd- EVO motherboard and a new AMD 965 BE processor build. I got 33C on idle when i fired up the system. Not bad for a $50 cooler. I assume temps will go down as Arctic Silver 5 cures.
Summary: Wasn't hard to install other than you have to take your mother board out to put the braket under the board. I guess the HX is too large to use without the extra support form a bracket under the mother board. seems well made and should hold up. Put it on a Intel 775 q9650 that i am overclocking to 3.6 and this heat exchanger keeps the temperature below 156F with a room temperature of 72F, thin air at high altitude, and the processor is at full load steady state.
Summary: So those of you looking at AMD boards, specifically the 890GX series, match sure you check for RAM clearance.
Pros: Great cooler that does its job.
Cons: My give problems to those who want to use this CPU cooler with RAM that have large heatsinks. I countered this by using GSkill's Eco series RAM. This RAM has small heatsinks, but stay cool due to lowered voltage requirements. Still gives good performance (DDR3, 1600MHz, 7-8-7-24) at only 1.35v.
Pros: The stock AMD cooler on my PhenomII x4 kept the processor at 45C idle and 65C under load. After I bought this my temps are 35C idle and 45C under load. This fits in my smallish Antec mid tower case with a tiny bit of room to spare. The included fan is quieter than my quiet case fans even at 2000RPM. This also has provisions to hook up a second fan on the other side of the heatsink for more airflow.
Cons: The fan clips will be in my nightmares for weeks to come. Once on, the fan is nice and secure, but trying to install is a pain. The slightest bump and they pop off the fan as you try to mount it. It's quite frustrating. This won't fit over RAM with huge heat sinks on top.
