XCLx321H Posted July 20, 2014 Share Posted July 20, 2014 Sirs, I recently purchased an RM 850 Power Supply, The type that the Cooling fan does not spin until 40% Load is placed on it. I have used it in Game and also carefully with Prime95 to try to produce a Load. And the Fan does not Spin. It's on a Haswell 4770K Processor Z87 MBoard system, Is there any Driver's that need to be installed or does Corsair Link need to be activated to get the PSU Working Properly. Thank you Sirs....

wytnyt Posted July 20, 2014 Share Posted July 20, 2014 you likely need to load it even more,,try a couple load tests simultaneously. if on startup up tho it does a self test where the fan spins for a few seconds.,,if it does this then its working...

I wouldn't worry about it unless your system is crashing from PS issues... Link to comment Share on other sites More sharing options...
XCLx321H Posted July 20, 2014 Author Share Posted July 20, 2014 Sirs, Not good. Tried 80% Load for a Half hour the Fan didn't budge. then I tried 100% Load for a Half Hour, Nothing. Simultaneously ? I don't get it ? run two Load producing Programs at one time ? or two of the same Programs ? Maybe I should run Corsair Link, or possibly RMA ? Any more Idea's would be great, Thank You...

wytnyt Posted July 20, 2014 Share Posted July 20, 2014 are your temps ok? do you get a couple seconds fan spin when you boot? if so i wouldnt worry about it as its obviously working... Link to comment Share on other sites More sharing options...
XCLx321H Posted July 20, 2014 Author Share Posted July 20, 2014 Sir, My temperature's are very Odd, They Jump from 30* (Degrees) Idle, to 60* (Degrees) with a 80% Load. Not the greatest Temps with a P/P H-100i. I have been using the machine now for 3 weeks at above Idle, with no Problems, so it must be working. But still I'd rather have the Fan cooling the unit Properly. Any Idea's Sirs... Not Spinning at all Upon Start nothing... Link to comment Share on other sites More sharing options...
XCLx321H Posted July 23, 2014 Author Share Posted July 23, 2014 Sirs, Still not Spinning, Brought the unit up to 100% Load, nothing for a Half Hour. No Spin at Start, Shut Down, Nothing. I have it mounted in a Carbide Air 450 in which it sits Sideways (Vertical). Could this be a factor ? If so what next ? Any Info would be great, Thank You.....

wytnyt Posted July 23, 2014 Share Posted July 23, 2014 its obviously working but even so running at 100% load still wont likely use 40% in wattage where the fan usually gets triggered.,,if however your adamant on making the fan work you can run a hard video stressing program and a cpu stress program at the same time,,hopefully this may produce 40% wattage use...

Corsair Employees Fauxbeard Posted July 23, 2014 Corsair Employees Share Posted July 23, 2014 Here's a blog that might shed more light about our RM-series power supplies: http://www.corsair.com/en-us/blog/2014/june/rm_fan-speed "A typical user would assume that their fan isn't working at all! After more than 20 minutes, the outer surface of the PSU housing reaches 40.9°C, the hottest we've seen, and this causes the fan to immediately spin up to 900 RPM. Of course, the fan only stays up here for less than a minute before spinning back down and leveling off at 620 RPM where it stays for almost two minutes before shutting off again.

XCLx321H Posted July 23, 2014 Author Share Posted July 23, 2014 Sirs, 40% Wattage use and run these two Stress test's simultaneously ? I'm sorry but I need more guidance (or instruction) on how this is done. Unigine Valley ? and Prime95 together. I'm beginning to think of RMA before I destroy the Unit, doing this. What is your thoughts on it. Thank you Sirs for all the help. Link to comment Share on other sites More sharing options...
wytnyt Posted July 24, 2014 Share Posted July 24, 2014 Corsair Bunny Foo Foo #5 blog will give you a good idea of stressing your psu. and yes i do mean to run both programs simultaneously in order to load the psu,,,theres no way you can damage the psu doing this but even if you miraculously do ,,well your entertaining the idea of a rma on a good working psu,least this way it would then be a valid rma;): anyways you honestly have nothing to be concerned about and if you do do a rma,,,youll get another psu that operates the same...

Conners Posted July 24, 2014 Share Posted July 24, 2014 Why specifically do you think you are destroying the PS doing this.... Sounds more to me like your trying to find a reason.... Link to comment Share on other sites More sharing options...
XCLx321H Posted July 25, 2014 Author Share Posted July 25, 2014 Sirs, I'm am worried about destroying the Unit, To tell the truth I do not understand how this process is done (two Stress producing programs at once). Knowing me I most likely would destroy the Power Supply. The PSU just sits there not Spinning. I've given the Fan a push too try jolting it, I also taped the PSU to try to get it to Spin. I'm just worried I might harm it. Thank you Sir's for the Info and Advice. Now what ? Link to comment Share on other sites More sharing options...

I'm just worried I might harm it. Thank you Sir's for the Info and Advice. Now what ? You would just start both programs at the same time. If I were you I would calculate just how much wattage you are using with the CPU, HDs, fans any thing that uses power and see approximately how much wattage it requires. I'm betting less than 40% of the psu at idle. (340 watts) You can calculate it here: psu calculator lite. By the way I roughly calculated it @ 100% load to be 500W. 40% of 500 would be 200W, so given that you would need approximately 70% (350W) load to make the fan spin. An RM650 would have been a better choice in my opine. Good Luck though... Link to comment Share on other sites More sharing options...
XCLx321H Posted December 23, 2014 Author Share Posted December 23, 2014 Sir's It took me this long to purchase the Corsair Link PSU Cable, Finally I have it. Now the Unit is shutting it self down, with a BIOS message on Boot. It says the PSU has experienced a "Power Surge" so by chance I disconnected the Corsair Link Cable from the USB Connector. and the message and the Shut Down's Stopped. Did I mention the Fan on the supply has not spun since I've had it ????? Possibly I'll purchase another Unit. Thank you sirs for the Advice...

Corsair Employees jonnyguru Posted December 23, 2014 Corsair Employees Share Posted December 23, 2014 Sirs, Not good. Tried 80% Load for a Half hour the Fan didn't budge. then I tried 100% Load for a Half Hour, Nothing. Yes. But 100% CPU load is not 100% PSU load. Your CPU only uses 84W under full load without OC. Sir, My temperature's are very Odd, They Jump from 30* (Degrees) Idle, to 60* (Degrees) with a 80% Load. 30°C CPU temperature is amazingly low! So what's your room temperature? The PSU fan operates on an algorithm of load, temperature and duration. If it's only 15 or 20°C in your room, that fan is never going to spin. Sir's It took me this long to purchase the Corsair Link PSU Cable, Finally I have it. Now the Unit is shutting it self down, with a BIOS message on Boot. It says the PSU has experienced a "Power Surge" so by chance I disconnected the Corsair Link Cable from the USB Connector. and the message and the Shut Down's Stopped. Did I mention the Fan on the supply has not spun since I've had it ????? Possibly I'll purchase another Unit. Thank you sirs for the Advice... Disable the "Anti-Surge" in the BIOS. This is an Asus specific product that measures voltages at the motherboard (not the PSU) and if it sees a 10% fluctuation, it will report that there's a "power surge".

XCLx321H Posted December 23, 2014 Author Share Posted December 23, 2014 Sir's, Under which heading will I find this "Anti-Surge "setting to Disable. I can't seem to be able to find it in the Users Guide. It's got to be in there somewhere. Will this cause any harm Disabling this setting. I'll take a look again. Thank You for the re-ply, It means a lot to me. Link to comment Share on other sites More sharing options...
Corsair Employees jonnyguru Posted December 23, 2014 Corsair Employees Share Posted December 23, 2014 It's in the BIOS under the "monitor" tab. Link to comment Share on other sites More sharing options...

DMaster Posted December 24, 2014 Share Posted December 24, 2014 I have a problem of another type with the fan in my HX850i. When PC is turned on, the fan does not spin as expected, and when I run LinX+Furmark, it starts spinning as expected (LinX or Furmark alone is not enough for the fan to spin). But when this stress-testing is over, the fan does not stop. Corsair Link shows Power Out = 70W...80W, but the fan continues spinning at 500...520 rpm, and spins until the PC goes to standby mode (after returning from standby it does not spin, of course). Is it a normal behaviour for HXi? I also have RM650, and its fan stops immediately after stress-testing is over (when used with the same PC configuration). Update: The next "investigation" showed that the fan stops but after at least 5 minutes of spinning while PSU is loaded with 70...80W. Link to comment Share on other sites More sharing options...
