hurricane28 Posted December 7, 2013 Share Posted December 7, 2013 Hi, I have a weird thing going on according the standard 2700 sp120L fans. they say that they have an speed of 2700rpm but i have 4 fans connected to my corsair link and none of them ramp up to 2700rpm. I also have connected them to my fan controller but it report the same speed as in corsair link. fan 1 goes to 2435 fan 2: 2556 fan 3: 2473 and fan 4: 2389 Are my fans broke? this is not even NEAR 2700rpm what corsair advertised... Can someone tell me what is going on? Link to comment Share on other sites More sharing options...
wytnyt Posted December 7, 2013 Share Posted December 7, 2013 any fan will have a tolerance based on construction,bearings and other factors so they likely wont reach stated rpm,even restrictions and case placement can affect total rpm's. theres usually a 10% tolerance so your fans are within specs.

hurricane28 Posted December 7, 2013 Author Share Posted December 7, 2013 Yes i know that but this is an very big difference don't you think? I mean all 4 have speeds that vary A LOT my best fan hits 2550 and my slowest is 2389... If they advertise speeds up to 2700rpm it must speed up to 2700rpm outside of my case and if they do not they lie about their fan speeds and such.. Also if they run much slower than the advertised 2700 they have an way less static pressure than they say as well. I do run push/pull tho so the speeds can vary but this is an ridiculously amount of difference in speeds. i assume they test their products to make such an claim tho.

wytnyt Posted December 7, 2013 Share Posted December 7, 2013 have you ran one in open air to check the rpm? of course tho even your worse fan is less than 50 rpm off of specs adjusting for tolerances... Link to comment Share on other sites More sharing options...

Because now i miss a lot of performance and basically they do not perform any better than the standard sp120's. I do want to point out that the second set of fans are the replacement fans that i got from Corsair because the first set had high pitch noise witch was an firmware fault instead of fan issue.

wytnyt Posted December 8, 2013 Share Posted December 8, 2013 hurricane28 you can submit a rma and get replacements fan as corsair almost always approves rma's as customer satisfaction is quite important to them however you will never get a fan that will achieve max rpm's in a real world application.,as theres just so many variables that will limit what a fan does i think the average for 2700 rpm fans is right at 2500 when installed.,at least thats my average for my 19 fans...

Does Corsair run each and every fan they sell through this test fixture, only a small sampling of production units, or only on an as-needed basis due to a potential problem?

hurricane28 Posted December 8, 2013 Author Share Posted December 8, 2013 update! I pulled my H100I out of my case and did a fan test, 2 fans were running at 26.. and two are running at 2730 exact the same speeds. So i mounted my best 2 fans on it and prestoo it performs just as good as when i was running in push/pull. I am running my CPU at 4.8ghz and i have set the fan profile in corsair link to quiet mode so i can't really hear them and still have very good performance! The max temp i saw was 56c so that is way below the max temp my chip can handle 24/7 I did run my chip at 5ghz before but there is not much of an difference in gaming or any other application that you will notice much so i backed off to 4.8 24/7. Another thing is that i get a way better temp when i exchanged the TIM with MX-4 Link to comment Share on other sites More sharing options...
wytnyt Posted December 8, 2013 Share Posted December 8, 2013 so free running they are well within spec/tolerance,this is good.also if against a radiator,dirt/dust in the rad will hinder the rpm... Link to comment Share on other sites More sharing options...
hurricane28 Posted December 8, 2013 Author Share Posted December 8, 2013 so free running they are well within spec/tolerance,this is good.also if against a radiator,dirt/dust in the rad will hinder the rpm... Yes they are indeed, i installed the 2 that were running at 2730rpm now. I do know that dirt, mesh and other things are restrictive and hinder the rpm, but what i thought was that the fans run that speed when installed, witch is stupid afterwords but hey, were all here to learn right :D: Also i am looking for a good deal for another case, because my 650D has not a very good airflow i noticed, i am looking for an 750D perhaps.

JKeifer Posted December 8, 2013 Share Posted December 8, 2013 i think Yellowbeard was just being amusing;): LOL. I would also say that machine really sucks or blows! Your choice. Also, fans run their absolute best in a vacuum! Link to comment Share on other sites More sharing options...

The 750 is a good air case if your GPU's use a reference style cooler. Otherwise,it's better suited to water cooling. If they exhaust in the case then your not going to like it over your 650D . Really your statement surprises me. Poor Airflow is one thing I cant complain about with my 650D Link to comment Share on other sites More sharing options...
hurricane28 Posted December 9, 2013 Author Share Posted December 9, 2013 . Poor Airflow is one thing I cant complain about with my 650D Okay, maybe i am doing something wrong than, can i ask you what your setup is and what fans you are using?
