Today we have a guest article from Martin who tested 30 different 120mm fans when mounted on a water-cooling radiator. He measured generated noise, cubic feet per minute of air moved with each fan, allowing for some impressive comparative result charts. If you arere looking for a 120mm fan upgrade, this article is a must read!
We revised our test setup, and submitted 33 popular CPU coolers to our rigorous new tests. Read on to find out which one cools the best, which one is the most silent, and most importantly, which one gives you the best value for your money.
The two demands we place on a case fan - to displace as much air as possible while producing the least amount of noise - are inherently mutually exclusive. In order to move more air, a fan needs to rotate faster, which produces more sound. The easiest way to make a fan more silent is to make it turn slower, but this will of course influence the amount of air it displaces.
This is where smart designers come into the picture. Case fan manufacturers try to increase the volume of displaced air by changing the design and number of the blades. We have seen a wide variety of designs: fan blades with notches like a golf ball, blades with a slant, and serrated blades. Nothing is too crazy to try. For each new attempt the manufacturer has a (vaguely) scientific foundation of why that particular design is better. In the end, it’s the performance that counts.
The same applies to the bearings used in the fans, something we've examined previously. In addition to the tried-and-proven ball bearings and sleeve bearings there are now exotic derivations such as rifle bearings, twister bearings, and so on. The goal is always the same - less noise. Again, it’s not the design but the end result that is important.
We teste iCEAGE Prima Boss II, the newer version of the good Prima Boss CPU cooler from 3R System. Will it overperform its predecessor? Check it out!
Let's get right to the point, 3Rsystem's Iceage 120 Boss II heatsink is currently one of the Top 5 heatsinks tested on Frostytech. Key to the success of this Korean-made heatsink on both AMD and Intel synthetic test platforms are five 8mm diameter exposed base heatpipes and a unique "X" pattern that places the heatpipes in the path of high velocity air from the coolers' 120mm fan. On top of that, the Iceage 120 Boss II heatsink utilizes dimpled surface fins which are intended to disrupt boundary layer laminar airflow.
3Rsystem's Iceage 80 Prima Mini is a compact CPU cooler that stands just 104mm tall. It's ideally suited towards compact PC systems, slim cases, or simply as a low noise cooling solution for energy efficient sub-85W processors. Given the burgeoning volume of 85W, 65W and 45W energy efficient processors, compact coolers like the Iceage 80 Prima Mini are certainly handy for any PC situation where there's not a lot of headroom
Viel Leistung auf sehr geringem Platz - besonders auch das stellt an Luftkühler in HTPC-Systemen hohe Anforderungen. Zu der reinen Leistungsfähigkeit kommt dann noch die Lautstärke, welche nicht zu hoch sein darf. Zuletzt kommt erschwerend hinzu, dass HTPC-Systeme sehr klein sind und wenig Platz für große Luftkühler vorhanden ist. Mit dem Noctua NH-L9i und dem Phanteks PH-TC90LS stellen sich zwei CPU-Kühler der Herausforderung, hohe Kühleistung gepaart mit einer geringen Bauhöhe abzuiefern.Wie sich die Alternativen schlagen, klärt unser Vergleichstest.
Für dieses kleines Tower Kühler Round-Up stellte uns Alpenföhn seinen Brocken 2, Noctua seine neuen NH-U12S und NH-U14S und Scythe den Ashura zur Verfügung. Wir haben diese vier CPU Kühler durch unseren Test Parcours geschickt und wollen nun zeigen was dabei herausgekommen ist.
We're happy to say that based on the test results we have a new CPU cooler to add to our lists of favorites: the Thermalright True Spirit 140. When you compare it to the Gold Award winners from our large round-up, Thermalright has the best overall cooling performance and its noise production is on par with the rest.
Wir haben einen neuen Artikel online, in dem wir 5 neue Kühler für die AMD-Plattform mit unseren bisher getesteten ca. 2 dutzend Modellen verglichen haben.
