This review is from: Enzotech MOS-C1 C1100 Forged Copper Heatsinks only
Pros: Quality copper
Included thermal tape works good
Other Thoughts: I test and review computer components, namely cooling solutions, as a hobby. My current project is learning more about GPU overclocking, and the available aftermarket cooling available to customers. The victim of my experiments have been an old GTX 460. To my dismay, I found that the aftermarket cooling solution I had purchased for the GPU did not offer proper voltage regulator module (VRM) cooling, so I purchased these to fulfill the duty.
Without these, even a small voltage bump to the GPU would cause instability. I could not even get up to the 1.062 V that most other review sites were able to get up to, before their cards throttled from overheating VRMs. With this product installed, I can handedly use the maximum voltage (1.087V) for the GPU. My maximum overclock was 920mhz, from the base 675mhz - that is roughly a 33% overclock.
So, I am pretty impressed with that. I even used the included thermal adhesive. I am going to purchase some more of these, and test them out on some other GPUs, as well as a motherboard.
Good LEDs (with on/off toggle)
Cons: Flexible plastic ring, in place aluminum.
Other Thoughts: I bought this for my other rig which has a Biostar A85W motherboard. There are three fan headers: one 4-pin CPU fan header, and two 3-pin system fan headers. The 3-pin fan headers on the motherboard do not allow for voltage control, so I purchased one of these to give a shot.
Overall, I am pleased. At full tilt, it is not completely inaudible, but you mostly just hear a slight whoosh of air. No annoying motor or bearing sounds. (I had to use a hot glass of water to heat the thermal probe up to make it run at full tilt.) It usually operates between 700-1300 RPM, depending on if my system is at idle or load. Anything below 1200 RPM you have to really strain to hear. Just having one of these fans decreases the internal case temperature by roughly 10C.
The thermal probe has a decently long wire that should be sufficient for most builds. I could see some people who have full ATX cases having an issue, but then it would be just too cumbersome for the rest. On that note, I think the temperature threshold for maximum speed is around 38C. Holding the sensor between my fingers was almost enough for it to reach maximum speed.
My only gripe is that they replaced the usual aluminum ring of the fan with a flexible plastic material. There is nothing actually wrong with it, it just strikes me as a cheaper money-saving effort, since these fans don't have the biggest market... and their market is more towards budget-orientated builds.
That said, these fans do fill a certain niche. They'd be great for those who want more case fans, and since they don't have the extra fan headers to support them have to hook them up directly to the PSU. (Why spend 25-40$ on a hardware fan controller, when for just over $25 you can have two of these?) If you also have a motherboard that lacks PWM and voltage control for fans, these are for you as well.
This review is from: ENERMAX T.B. Silence UCTB12P 120mm PWM Function Case Fan
Pros: Very Affordable
Cons: Kind of an energy hog. (Almost five watts.)
Other Thoughts: This is a well-rounded fan that can be used either as your standard intake/exhaust, or on a heatsink/radiator and will give good performance in either case.
On a heatsink, the fan may fall short of premium performance, but to surpass it you will be easily spending $5-10 for marginal gains; a couple degrees at most. That is only discussing absolute thermal performance, and not taking into account how loud the fans might be. On a heatsink, the fan does a good job of remaining unobtrusive, making mostly a type of "whoosh" of the sound of moving air. That sounds kind of silly, but it's better than a high-pitched whine or insistent clicking/ticking that some other fan motors make when at full tilt.
As a case fan, you'll seriously be hard-pressed to find appreciably better, both in acoustics and performance. Off of a radiator, the acoustics are pretty top-notch; only above 1200 RPM is the fan really noticeable. If you want, though, you can dial the fan all the way down to 500 RPM, however.
The fan bearing allows you to mount the fan horizontally, unlike a sleeve bearing, which are still around for some odd reason.
These are the first types of fans I recommend to anyone who I come across looking for replacements, or new fans to try. They are really hard to beat for their price point, and, unless you're an enthusiast needing to eke everything out of your rig, the extra money you'll spend on another product won't be worth it.
