Product Description

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).

I've tested, written about and used many low profile coolers over the past couple of years building mini-ITX HTPC and office systems for clients including:

Silverstone NT07-1156
Gelid Slim Silence i-Plus
Titan DC-155A915Z/RPW

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!

Although I just installed this unit today there is nothing but good news to report (but if things change I'll follow up). This cooler was necessitated by the total failure of the fan of my previous Silverstone NT07-1156 and the unavailability of a replacement unit. This cooler is amazingly compact and very heavy for its size, undoubtedly due to the almost solid-copper construction and thick baseplate. Running with a 3.4gHz i7 the cooler keeps core temperatures at least 12 degrees away from the 98-degree max, similar performance to the previous Silverstone. This might not seem great but the processor is running flat out at 100% on all four cores and eight threads running the BOINC client 24 X 7 in a very compact M-ITX enclosure along with a double-wide video card. Thinking about it, this cooler might just be outperforming the previous one since I reduced the case fan speed from 100 to 70% during testing and the temperature didn't suffer.

Bought one of these to conserve space in a Mini-ITX build for a family member and paired it up with an Intel Core i3-4160. First thing I noticed was that this thing is an EXTREMELY low profile cooler. Like, surprisingly short, even compared to my expectations--it's just a little taller than the diameter of a US quarter once installed! It is also very heavy for it's size, but that is to be expected as it is almost entirely copper.

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.

I love this heatsink and fan, it's very heavy for its size and I like the fact that it uses the stock clips like the Intel CPU fans.

But this heatsink will not work with the Silverstone Tek Aluminum Top Cover/Steel Body Thin Mini-ITX Media Center/HTPC Case PT13B

It's too tall for the lid to close so I have to find something else.

Had problems cooling a Intel Core i3-4360 Processor (4M Cache, 3.70 GHz) BX80646I34360 in a Raidmax ITX Computer Case with Power Supply Case ITX0907BP case.

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.

I had this cooler in a 1U rackmount chassis and it kept my processor form overheating but just barely. It got VERY hot in the system and I eventually replaced it with a Dynatron K199 which cools MUCH better although it is louder.
