S4028-6K (5 Pack)

so far performance two minds but they seem ok, first of all when first turned on pc i could not hear them, they so quite i even went in to bios and downloaded software then had very close look with light and they were turning, so more quite than i expected, good to about 3500-4000rpm after that you really know they are on. so far i do like them but performance its hard to tell as they not only fans im running , build of them seems good, the price is good and power well it not to crazy , nothing like the 8k 120mm fans at nearly 30w each, these small fans use far less than that but still got a powered hub, reliability well not had them long but arctic they known to be pretty good but have used them for 8-20 hours at a time every day for around past 3 months they still seems good

Very cool

Absolutely perfect product, easy connection design with a standard 4 pin pc connection, works very well especially for its size, it’s, 4x4cm front dimensions make it fit well with basically anything you could want it for. Additionally, considering it’s size and 6,000 rpm potential it can hit roughly 3500 rpm with very little sound, and shoves and impressive amount of air at 6k rpm

I needed a 40mm fan that could move some air to help cool my Tesla P4 in my home server; that card is passively cooled and designed to go in a server case with lots of air movement, so it gets really hot the second you try to run a game on it or any ML work. I 3D printed a little bracket, and screwed this fan to it then push fit it to the card; I run it at about 38% which is the power level I can't hear it at, and it still pushed enough air to keep the card cool in use. These are a little noisy when you crank them up, still not as loud as rack server fans, but you don't want them in a quiet room with you at anywhere above 40%. They're 4-pin so they're software controlled and show their RPM. Why 5 then? Well I only needed 1, but it was only a few quid more to get 5 of them compared to buying 1, and 1 fan was something like £20, so I thought I might as well get 4 spares...

Purchased to refit an old server (project on pause due to the extortionate price of electricity at the moment) - the fans are of a good quality and move a decent amount of air - I would recommend getting the high RPM fans for server use though - I'm currently using these fans in my network switches and 3D printers and have had no issues.

I bought these to replace the fans in a Cisco switch. The exiting fans spin up to like 10K are are way overkill for what the switch actually does, plus I was adding 2 fans where the existing one had 1 fan. I figured I could get the same airflow with 2 fans running slower, therefore reducing the noise. Given how expensive Noctua are, I figured this 5 pack would be worth a shot given I have a few switches to try out. Was I correct? Well perhaps in terms of airflow, as that is one redeeming feature of the product... it's very good for the size, but the problem is that these fans are annoyingly noisy. They have a horrible whining sound, even if you reduce them below the 6k RPM that they ramp up to at max. I'm not atually sure they were less annoying that the stock fan. What is the real downside to these fans is the plastic, and the design of the shroud. It's SUPER brittle, the holes are small, and they go the full length of the fan. This means you have to use the provided screws, but the heads on them are smaller than the typical fan screw so they end up sliding through the hole. I tried using a slightly bigger screw, the plastic cracked and because the screw hole is a tube from the front to back, instead of just being a tab, it broke a huge chunk off the fan making it unusable. I now basically have £25 worth of useless fans and am going to end up with Noctua anyway...

Gillar verkligen dessa fläktar, använder dessa som ersättare i TP-Link TL-SG3424P. Det jag inte tänkte på var att dessa är 28mm tjock och inte passade på alla positioner då standarden är 20mm.

montate 3 nel case per avere un maggiore flusso di uscita, sono delle turbine, e a 2000 giri non le senti neppure.

Todo bien. Precio razonable.

Super rapport qualité/prix. Bon débit d'air pour cette dimension

Die ARCTIC S4028-6K nutze ich zur Belüftung eines Netzwerkschranks. Die Lüfter laufen zuverlässig und lassen sich sauber per PWM über den gesamten Drehzahlbereich regeln. Bei moderaten Drehzahlen sind sie für diese Baugröße relativ leise, bei höherer Drehzahl entsprechend leistungsstark. Verarbeitung und Lager machen einen soliden Eindruck, bisher keinerlei Ausfälle oder Unregelmäßigkeiten. Für dauerhaften Betrieb in Technik- oder Serverschränken gut geeignet.
