The Dynatron T459 is designed for compact cases, particularly those where the Intel stock LGA 1155 CPU cooler is unable to fit due to height restrictions. LGA 1155 (Socket H2) design, compatible with the 2nd Generation (Sandy Bridge) Intel Celeron, Pentium, Core i3/i5/i7 and Xeon processors. Simple push-pin design and pre-applied thermal compound for a quick and secure installation. Low Profile Design With a mounted Z-height of only 27.8mm, this CPU cooler can fit in just about any case (including 1U rackmount cases and ultra- compact Mini-ITX enclosures e.g., M350, Morex 557).

In terms of cooling performance, it seems to be about par with (maybe slightly weaker than) the Intel stock cooler for an i3-4160, from my experience. Keeps the CPU in the low 40s at idle and between the mid 50s and 60s at "moderate" working loads (which I'm defining in this case as 30-50% total CPU usage) with the fan set to dynamically ramp up according to BIOS defaults. The fan is surprisingly quiet (almost silent most of the time on dynamic fan settings), even when I manually set it to 100% to see how long it could handle Prime 95 as a "worst-case scenario" stress test.
Mind you, this IS an extreme low profile cooler and even at it's best, an i3-4160 at stock will push northwards of 80 degrees at around the five minute mark of Prime 95's standard stress test, so if you're looking for a heatsink for overclocking or gaming where you'll often have the CPU running at 50-75% load or more for long stretches, then this is NOT the cooler for you. However, for a low-profile, light usage (email, web browsing, and netflix) computer or HTPC, this cooler can get the job done.
If I had the option, I would give this cooler "3.5 stars" for its impressively short stature and whisper-quiet operation, but only adequate cooling performance for low-intensity applications (an i3-4160 was warm, but still within acceptable temperature ranges at moderate load) and overall performance leaving me only comfortable using this cooler with CPUs up to a 54W TDP maximum despite it being rated for up to 73W. In addition, one little nitpick concern for me going forward is mostly a matter of personal taste, but the heatsink is secured using those plastic push screws you see on Intel stock coolers. They're more than strong enough to hold the heatsink's weight and keep it snug when affixed properly, but I still would have preferred to see metal screws and a backplate for the extra peace of mind it gives me knowing the heavy hunk of metal I just attached isn't going anywhere. These factors do amount to a neutral 3 stars for the formal ranking with the review instead of up to a positive 4 stars; but I am overall satisfied with the cooler for the purpose I bought it.
TL;DR: this is the lowest-profile heatsink I've ever personally encountered and it's cooling performance is acceptable for light-usage computers (which was what I used it in) or possibly HTPC applications. HOWEVER, if you are looking to keep your mini-ITX gaming rig cool, this almost certainly not the cooler for you; and I personally would not recommend this heatsink be paired with processors with a TDP of any higher than 54W.

and this one is simply the best one out there under 37mm. First, the fan is the quietest among them all. Even the best still have a bit of a buzz but the Top Motor fan included on this one is smooth with no buzz. You have to put your ear within a foot of it with the top of the case open to hear anything. Second, the quality of this heatsink is the best. It's full copper and it comes with the thermal paste already applied. It's very heavy and easy to install with no backplate required. Third, and most important, it does a fantastic job keeping processors cool in these tiny little cases. I use it for builds in the Realan E-i5 (75mm high) and E-K3 (72mm tall) which are very small mini-ITX cases. For the E-K3, that the cooler uses the standard mounts is very important because the backplate on other coolers interferes with the VESA mount while the T459 does not interfere at all.
The only con is the way the fan is mounted. It's screwed into the heatsink from underneath meaning if it does fail and need to be changed, the heatsink will need to be removed.
For Intel builds in these mini-ITX cases I will use no other as long as these are available. I've found nothing quieter or better cooling in this size at this price. Perfect!
Idled at ~55C, there was no room for any decent airflow, with the DVD drive installed.
Went with a Noctua Low-Profile Quiet CPU Cooler for Intel 115x Based Retail Cooling NH-L9I and no problems.

Barely can hear it, while effectively cooling the CPU.
A must for HTPC build.
