Glacialtech Igloo 5620 PWM Heatsink Reviewed on Frostytech

BY: Frostytech.com — Tue, 21 Feb 2012 14:31:35

"While the Glacialtech Igloo 5620 PWM heatsink ships with one 92mm fan capable of operating at 2300-800RPM, additional fan clips are supplied for a second user-supplied 92mm fan to be installed if desired. The base of the heatsink makes use of exposed heatpipes to leverage the rapid heat conduction qualities of these thermal devices. Given the relatively compact height of the Igloo 5620 PWM heatsink, it should fit into a good variety of PC cases which are off limits to the vast number of +160mm tall heatsinks."

Coolermaster Hyper 612 PWM Heatsink Reviewed on Frostytech

BY: Frostytech.com — Tue, 21 Feb 2012 14:27:39

"On the test bench today is a boxy tower-style processor heatsink from Cooler Master called the Hyper 612 PWM. This is a pseudo-quiet cooling heatsink built around six, 6mm diameter copper heatpipes and a single 120x120mm PWM fan. The fan rotates at 2000-600RPM and offers at best, excellent thermal performance. At the slowest fan speeds you can expect very quiet but generally average performance from the Hyper 612 PWM heatsink."

Noctua NH-L12 low-profile cooler for Small Form Factor cases

BY: Frostytech.com — Tue, 21 Feb 2012 13:46:11

Noctua today presented its new NH-L12 low-profile cooler for Small Form Factor cases and HTPC environments. The NH-L12 features a flexible NF-F12 (120mm) / NF-B9 (92mm) dual PWM fan setup that can be configured either for full performance in dual fan mode or extra-low profile (66mm) with the top fan removed.

"The industry trend towards Small Form Factor and Home Theatre PCs is well-established, but there's still a lack of suitable high-quality quiet CPU coolers", explains Mag. Roland Mossig, Noctua CEO. "Building a powerful PC always requires a capable CPU, which in return demands a competent cooling solution. But who wants his HTPC to sound like a jet engine? This is precisely where the NH-L12 steps in."

Thanks to its exquisite dual fan setup consisting of Noctua's highly optimised NF-F12 (120mm) and NF-B9 (92mm) premium fans, the NH-L12 pushes the bar in terms of low-profile quiet cooling performance. Alternatively, the NH-L12 can also be used with the NF-B9 92mm fan only in order to reduce the overall height to 66mm. This way, the cooler is suitable for many typical �ATX or Mini-ITX enclosures and ideal for whisper-quiet HTPC systems.

The NH-L12's NF-F12 and NF-B9 fans support PWM for convenient automatic speed control. In addition, the maximum fan speed can be reduced to 1200/1300rpm using the supplied Low-Noise Adaptors for even quieter operation. Bundled with the award-winning NT-H1 thermal compound and Noctua's SecuFirm2� multi-socket mounting system, the NH-L12 packs everything a premium quality quiet cooler needs into a highly compact package.

The NH-L12 will be available immediately at a recommended retail price of EUR 49.90 / USD 59.90 [NOCTUA] via [Frostytech.com]

Nofan CR-95C IcePipe 95W Fanless CPU Cooler Review

BY: Frostytech.com — Tue, 21 Feb 2012 03:31:57

"Pretty apt name when you think about it "Nofan" produce passive and 100% silent CPU coolers, you are probably already think if its passive it has to be really hot though right? Well that's what we thought to be honest, but you really need to read on because this review might surprise you a bit!Things to point out really are that with it being fanless that means that its 100% silent and wont get clogged up with dust over time and for this reason the temperatures should not creep up due to there being no dust starting to insulate the heat sink. So although we had to alter our testing to fit within the supported hardware of the CR-95 it has performed well enough to shock us...." [OVERCLOCK3D] via [Frostytech.com]

Shagon' ARC-118

BY: Frostytech.com — Fri, 17 Feb 2012 09:02:00

Vor kurzem pr�sentierten wir schon ein Review zum Neueinsteiger Shagon'. Der AHC-118 baute auf einen 120-mm-L�fter und sechs Heatpipes. Des Weiteren war er von den Abma�en kein Winzling und kann bei einigen Geh�usen zu Problemen f�hren. Shagon' hat deswegen zeitgleich einen kleineren K�hler ver�ffentlicht, den ARC-118. Dieser baut auf einen 92-mm-L�fter und nur vier Heatpipes, die ebenfalls wie beim gro�en Bruder mittels H.D.T. die Abw�rme direkt vom Prozessor aufnehmen. Was man vom kleineren der beiden K�hler erwarten kann und ob er besser abschneidet als der AHC-118, kl�ren wir im folgenden Review. [DEXGO] via [Frostytech.com]

Noctua's DH-14: Air Cooling Keeps Up With Liquid?

BY: Frostytech.com — Thu, 16 Feb 2012 09:03:00

A few months back, we examined the performance of four liquid coolers for the Sandy Bridge-E socket LGA 2011 platform: Corsair's H80 and H100, Maingear's Epic 180, and Intel's own reference cooler. Liquid coolers are popular with high-end OEMs and some enthusiasts, but they aren't cheap -- and there's a certain group of enthusiasts who aren't comfortable with flowing liquid in their systems. Recently, we spoke with the team at Noctua, who offered to send us one of its high-end air coolers for comparison. We've been curious about the company since it came across our radar with its upgrade offer for anyone upgrading to Socket 2011 last year. The Noctua DH-14 is a mammoth air cooler that competes performance-wise with many self-contained liquid coolers. Check it out... [HOTHARDWARE] via [Frostytech.com]

Cooler Master GeminII M4 CPU Cooler Review

BY: Frostytech.com — Wed, 08 Feb 2012 09:00:00

Usually when a CPU cooler is reviewed here at the Shrimps we are talking about high end big and bulky models. Dual towers, triple fan equipped, the bigger the better. But what about for them that are building a high performance HTPC or eg a mini cube ? Do they have to rely solely on the included boxed coolers ? I had the privilege to build a Mine LAN PC inside a Lian Li V353 Cube shaped case. Most important factor was the build's size, not at the cost of performance. The choice of components was pretty high end : Asus Maximus IV Gene, Intel 2600K, 16Gb of Corsair ram, 120 Corsair GT SSD and a Nvidia GTX560 GPU. More than suitable for casual gaming purposes. After the build was completed, we noticed, during stability testing, that the CPU got pretty hot. And it was still running at out of the box speeds. Time to look for a beefier cooling solution Our eye fell onto Cooler Masters' latest low profile CPU cooler : The GeminII M4 CPU cooler. [MADSHRIMPS] via [Frostytech.com]

Thermal Interface with a Patterned Structure

BY: Frostytech.com — Wed, 01 Feb 2012 01:50:08

Curiously, I had a discussion with a thermal solutions manufacturer during Computex Taipei, circa-2003/04, about nearly the very same concept that Patent 7282799 - 'Thermal interface with a patterned structure' details. That is, to create very thin, shallow grooves in the base of heatsink to enable the maximal amount of excess thermal interface material to escape from between the heatsink-to-integrated heatspreader contact area.

Physics of course gets the original patent on this, as thermal interface material will naturally do the same thing, given time, heat and clamping force. You can see examples of this after removing a heatsink, provided the base of the heatsink is flat and the clamping forces even. If these conditions exist, you'll see a pattern in the shape of a X going from corner to corner in the remaining thermal goo, with fine fractal patterns sub-dividing the remaining area ad infinitum.

Patent 7282799: Worth the read.
