Product Description

Ultimate Fanless CPU Cooler FX100. With Zalman's innovative technology, the FX100 is designed to utilize natural convection where the heat sink passively transfers the heat to the surrounding. The hot air is then exhausted out of the chassis with the help of chassis fans. And, due to its passive and efficient operation, several factors that contribute shorter life span in electronics (such as vibration, dust, and heat)have minimal impact, which makes the FX100 one of the most durable CPU cooler out in the market.

5.0 out of 5 stars This CPU Cooler works great if installed/tightened according to the instructions
Reviewed in the United States on January 2, 2015

This CPU Cooler works great if installed/tightened according to the instructions. It is a little difficult to install compared to installing the stock cooler. You will need a longer phillips (cross-point) screwdriver and some patience to reach the screws. Also, make sure you have proper clearance around your CPU; if any components are in the way (i.e. heatsinks, capacitors, etc.) when installing the bracket, you will not get good contact with the CPU and results in a loose connection. I have it installed on a Gigabyte X58A-UD5 motherboard and everything fits perfectly.

The cooler is designed to operate fanless on a CPU with a max TDP of 95 watts. I have it installed on an Intel 980X Extreme Edition CPU, which has a stock max TDP of 130 watts. According to the instructions, Zalman emphasizes that a 92mm fan is required for LGA 1366 and 2011 CPUs. I installed a Noctua NF-A9 PWM Premium 92 mm Fan and the CPU temperature is 38 to 40 degrees celsius on idle and 55 to 60 degrees under full load, while still maintaining a near-silent db level. These temperatures are with an overclock of 4.2 GHZ.

I was a little skeptical after reading some reviews on-line, but I am glad I decided to go with this cooler.

2.0 out of 5 stars Poor Design
Reviewed in the United States on September 27, 2013

I purchased this cooler for a Haswell i5 rated for 75 TDP. The processor was reaching unacceptably high temperatures while gaming. Also, Once the CPU cooler is installed/attached to the processor, it can be twisted left and right. It also shifts/spins left or right on its own because of an unequal weight distribution. You can read some reviews on Newegg about this.

If you are willing to put up with what I had mentioned, you'll likely be satisfied with it. It feels and looks high quality.

Unfortunately, I'll be using the factory heat-sink until it can be replaced.

5.0 out of 5 stars Heatsink is amazing. In short
Reviewed in the United States on March 4, 2015
Heatsink is amazing. In short, I'm running an i7 processor overclocked, raid hard drives, dual SLI video cards (and more) without a fan in the heatsink--I game with no issues. You MUST install this properly as instructed. If you don't have good contact between between the heatsink and the processor then it will overheat. Use a razor thin and even amount of the thermal compound that comes with it. My computer is completely silent...love it!

Ottimo dissi che permette di raffreddare la CPU completamente senza ventole.
Per sicurezza, ho montato una Noctua NF-B9 PWM presa sempre qui su amazon. Sulla scheda madre è possibile settare la ventola in modo che parta dai 70° in sù.
Testato con i3, la ventola non parte mai (la CPU è sempre fresca).
Occhio al montaggio, è possibile che sia necessario inserire una rondella (quelle che si prendono in ferramenta) tra il ponte che fissa il dissi e la base del dissi.

Que dire sinon que c'est le must ! PLUS AUCUN BRUIT ! mieux que le watercooling que j'avais avant et qui commençait a faire pas mal de bruit.
mon Proc est un intel core i7 2600K et 95W de TDP donc la limite accepter pour ce ventirad sans le ventilo.
En jeu, au bout de trois heure de burn avec tomb raider au max dans ma tour super mal ventiler , mon proc n'est jamais monter au dessus de 59°C tout ça en silence (relatif car du coup je me suis rendu compte du bruit que fait ma carte graphique :)

Un bémol pour le montage : il vous faudra OBLIGATOIREMENT un tournevis cruciforme dont la tige sans le manche fasse AU MOINS 15 centimètres sinon vous serez obliger comme moi d'aller en acheter un ! En effet il faut passer par l’intérieur du radiateur pour le fixer a la carte mère.

Avec le bon tournevis ,aimanter si possible , le montage devient très facile.

Je le recommande chaudement

Einen  Intel Sockel 1155 Core i3 Processor i3-2120 Box Prozessor (3300MHz, L2/L3-Cache)  passiv zu kühlen war eine suche mit glücklichem ausgang.
Für ein solches unterfangen bedarf es einer kühlkonstruktion mit üppiger radiatoroberfläche, großzügigem lamellenabstand und effizienter wärmeaufnahme. Der südkoreanische kühlerspezialist Zalman, um den es aufgrund erstarkter konkurrenz in diesem segment immer ruhiger geworden ist,hat eine neue referenz für lüfterloses prozessorkühlen am markt positioniert.
Der FX100 ist ein kühler mit sechs separaten lamellenkörpern, welche lediglich durch ein einzigartig anmutendes, sauber verlötetes geflecht aus heatpipes in verbindung stehen.Der FX100 erhält seinen beinamen „Cube“ aufgrund seiner nahezu einheitlichen kantenlänge von 156mm, die lediglich in der höhe um einen weiteren millimeter abweicht. Der eigentliche radiator beginnt dabei erst ab einer höhe von 45mm, sodass periphere bauteile im sockelbereich problemlos passen sollten.
Der schwarze nickelmantel verleiht dem cooler zudem eine sehenswert einheitliche optik, die lediglich durch die aufgesteckten kunststoff-ecken sowie das geschraubte mesh-gitter an der oberseite des kühlers unterbrochen wird.
Sollte die leistung des FX100 nicht ausreichen, lässt die knapp 760 gramm schwere konstruktion die kombination mit einem optionalen 92-mm-lüfter zu. Dieser wird, nach vorübergehender demontage der mesh-abdeckung, zwischen die beiden inneren lamellentürme geschoben und mit hilfe der beiden metallklammern aus dem lieferumfang fixiert. Hält bombig, habe ich auch getestet.
Die montage der ganzen konstruktion ist, nachsichtig ausgedrückt, etwas für feinmechanikerfinger. Das es Zalman nicht für notwendig erachtet, das zur montage notwendige werkzeug beizulegen, finde ich angesichts des preises von über 70 Euro kaum akzeptabel. Immerhin wird ein kreuzschraubendreher benötigt, der eine mindestens 14 cm lange, dünne spitze besitzt, so dass man problemlos zwischen den äußeren und inneren lamellenbereichen agieren kann.Ich habe so ein teil in meiner werkzeugkiste, da ich solche aktionen von berufs wegen häufiger mache.

Schlussendlich bin ich mit der passiven kühlleistung in meinem Apple-G5-casemod zufrieden. Zielgebung war es, ein passiv gekühltes systemsetup um geräuschemissionen zu vermeiden. Optisch konnte ich zum jetzigen zeitpunkt nichts besseres finden. Allerdings sind alle plastikanbauteile von mir nicht verbaut.
Wer genug platz in seinem case hat, kann mit diesem kühler eine menge hitze vom prozessor ableiten. Ich würde ihn wieder kaufen.
