is gelid hydro dynamic bearing a decent bearing or not?

post #1 of 9
Thread Starter 
I'm trying to find a fan I won't have to keep replacing in a system that is on but idling for weeks at a time without paying a gigantic chunk of change. Seems you can get a 4 heat pipe 120mm tower in the ~$20 range, plus the cost of the fans that come with it.

I'm looking at the Gelid tranquil 4 @$30. if the fan is decent durability wise it's a win. Any opinions?

here is a good article on computer fan bearings, read down about 4 sections and it explain's the Hydro-Dynamic bearing, the article starts with Fluid Dynamic bearing but if you read this article you will see there are different types of these bearings with one being a Hydro-Dynamic.
per the article the Hydro-Dynamic is a good bearing, it just has a different design then the Fluid-Dynamic bearing and cost less to manufacture.

So there are five different competitors listed, (ignoring twister bearings and whatnot) but no info on whether or not they actually work. Argh!

well ilve had experience with traditional rifle bearings, and they suck. The definition seems to have changed though. It used to be a rifle bearing had a single spiral cut around the bearing, pulling the oil up through the bearing, so that it could be used horizontally without immediately crapping out. They have the same loudness over time issue as sleeve bearings.

I do know from experience that "official" FDBs will outlast a sleeve 4 to one, and stay quiet the whole time. I wound up pulling the trigger on a hyper 212 evo about an hour ago, It was just too cheap. 25 bucks smile.gif. At that price, I can just let it disintegrate and buy whatever afterwards.
