3 out of 5 eggsGreat cooler, Worse than useless heat sink compound

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

Pros: Best low profile cooler for keeping case noise low. Uuuuuge, slow spinning 120mm fan compared to most lo-pro coolers.

Cons: DO NOT use the heatsink compound that comes with it. Mine was this runny grey mess, more like elmer's school glue than heat sink compound. My processor was thermal throttling within 10 minutes and eventually just crashed. Replaced with my emergency tube of generic white HSC and all was well.

Other Thoughts: Yeah. I know, I know. Never use HSC that comes with the cooler. Well I was out of Arctic Silver and my Cooler Master fanboyism got the best of me. I hope it was just my package, until now I've had nothing but awesome products out of them. Still a fanboy, just not as rabid as I used to be :-/

Pros: -Does a great job keeping the processor cool and running.
-Excellent and low profile design,
-Looks good in a windowed case.

Cons: -No cons

Other Thoughts: The fan is kind of awkward the way it mounts to the heat sink fins. Be careful and pay close attention taking if off if you need to.

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.

4 out of 5 eggs

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.

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.
