5 out of 5 eggsIncredible value and flexibility

This review is from: Cooler Master GeminII M4 - CPU Cooler with 4 Direct Contact Heatpipes

Pros: Price to performance, aesthetics, low noise output, ease of installation. This cooler represents fantastic performance to price. It is very easy to install, the footprint allows for plenty of clearance for high profile memory as well as not impeding on the first PCIe lane area.

Cons: None that I can think of.

Other Thoughts: I've used this cooler in a number of different builds for clients. A low price point combined with great performance keeps me coming back to this unit. The downdraft style lets me fit this into many slim cases while retaining very strong cooling capability. Air movement over heatsinks and nearby components in low profile cases is fantastic.

This review is from: Cooler Master GeminII M4 - CPU Cooler with 4 Direct Contact Heatpipes

Pros: Installation was easy, even comes with thermal paste. I'm using this on AMD 8350 with 2U Case which keeps relatively cool around 50 Celsius. Since I don't have much room for air in take i'm using additional fans to supply air to the cooler.

Cons: The fan good be a bit better as it's plastic, will see how well it functions overtime. Might replace it later with another slim fan.

1 out of 5 eggsLGA 2011 Motherboards

This review is from: Cooler Master GeminII M4 - CPU Cooler with 4 Direct Contact Heatpipes

Pros: It is Slim

Cons: Despite the box advertising 2011 comparability the screws are two sort or the brackets are too high. It IS NOT COMPATIBLE with 2011 CPUs out of the box.

Other Thoughts: Not sure how fix a logistic issue like this, these seem like the brackets where not tested ahead of shipping the product.

1 out of 5 eggsTerrible

This review is from: Cooler Master GeminII M4 - CPU Cooler with 4 Direct Contact Heatpipes

Pros: Somewhat quiet, keeps cpu cool.

Cons: The heat sink fan has very poor mounting latches. Continuously slides down heat sink over time, contacting my GPU. Could not find a way to keep it secure. Ended up tossing it and reusing stock heatsink.

Manufacturer Response:

Dear Valued Customer,

We apologize for the trouble that you are experiencing with the Geminii M4. The Geminii M4 does have a 2 year warranty so you can submit a part request for the replacement fan clips.

Please contact us if you have any further questions.

Respectfully,

1 out of 5 eggsTerrible cooler

This review is from: Cooler Master GeminII M4 - CPU Cooler with 4 Direct Contact Heatpipes

Pros: low profile

Cons: terrible heat transfer, loose fan, rattles when running

Other Thoughts: I am using this on an AMD A10-7700. At 15% load, the CPU temp was 110*C. I thought I did something wrong. I took off the cooler, reapplied all the thermal paste, double and triple checked my steps and installed it again. What do you know, over 100C again. I am using this in a CoolerMaster Elite 110 case, with an upgraded 140mm fan feeding the front of the case. There is NO reason for this CPU to be running this hot under such a small load. Useless cooler, will not buy a low pro cooler from coolermaster again.

2 out of 5 eggsCould've been good, apparently received a dud.

This review is from: Cooler Master GeminII M4 - CPU Cooler with 4 Direct Contact Heatpipes

Pros: It's quiet.

Cons: For AMD systems, it requires its own backplate for no good reason. This requires removing the board from the chassis, which for most compact systems, means unbuilding the entire computer if you're upgrading an already-built system.

The mounting bracket needed for AM3+ was received bent and had to be bent back before it could be used.

To my surprise, after a difficult and prolonged installation, it struggled to cool the CPU (FX-8370) under moderate load, or even under idle. I used MX-4 thermal compound and made sure it was properly installed and seated flat against the CPU. I took it off, and it would appear the heatpipes weren't aligned/level with the metal base, leaving large air gaps between the cooler and the CPU.

I at least kept the fan because it worked well. The rest went into the trash.

Other Thoughts: I probably got very unlucky, but all that went wrong here screams terrible QA from Cooler Master. A massive disappointment.

Manufacturer Response:

Dear Valued Customer,

We apologize for the trouble that you are experiencing with the GeminII M4. Majority of our coolers come with a backplate that you must use so I apologize if this requires you to remove the motherboard.

I would definitely suggest contacting us in the future so that we can assist in recommending an appropriate cooler. The GeminII M4 will not be able to cool an FX-8370 so this is why you are having cooling issues.

For that CPU, I would suggest looking at a Hyper 212 EVO or a Nepton 120XL.

The GeminII M4 does come with a 2 year warranty so please contact us if you need any replacement parts.

This review is from: Cooler Master GeminII M4 - CPU Cooler with 4 Direct Contact Heatpipes

Pros: Cool design. Very Quiet

Cons: Bearing went out after 5 months. Called support. They were back ordered 3 weeks. Couldn't wait that long. So I had to buy another one because of my case design. I don't recommend this product unless you have limited room.
