Let's hope that click was the latch on the 24 pin connector, mating and closing with the motherboard portion. It was. I was listening for the click the first time, but didn't press the issue. I'm trying to un-train myself from my (bad) habit of over-tightening things. I will try the program you suggested for testing. By the way, I did notice that my GPU has a hook on it. I guess that means you slide it towards the screws a bit before you try to pull it out? Cheers, Bill |

Cheers, Bill My advice on the video card retainer, is figure it out while you can still see it :-) There's nothing worse than not being able to see in there, and barely being able to get a finger on it, then trying to figure out what you're supposed to do. Even after you've examined the mechanism in the light, you might still have trouble. The slide ones should be less of a challenge. You can see the heel in a picture of a video card here. http://images17.newegg.com/is/image/newegg/14-131-338-Z11?$S640$ It's that thing on the lower right. On the spring loaded ones, a round "button" fits over top of the heel, and prevents the heel end from lifting. You pull back on the spring, moving the button out of the way, so the heel can rise up. In the slider type retainer, sliding the slide mechanism towards the faceplate, is the "locked" position. Sliding the slider mechanism away from the faceplate, removes the slide from over top of the heel, so the heel can rise up. HTH, Paul |

A "tiny white lever" was really tough to see I'm lucky I didn't break anything! ; ) My new one has a hook, just like in your picture. I will strive to keep it in mind if I ever need to remove it! Tonight I'm "screwing around" transferring files (some mp3's I purchased from Amazon.com just don't want to go), and transferring my email files (I can make it work...it's just not working as nice as it should--yet). Thanks, Bill |

Authors web site... http://www.almico.com/speedfan450.exe Paul Thank you very much. One more question please. The fans on the H105 are "PWM". Do you think it is normal for 1 fan of the 2 radiator fans on the H-105 to run while the other sits and maybe just "jiggles" a little (at low speeds). That is what drew my attention to it in the first place, is that I could hear some very, very light sounds (of the 2nd fan sort of trying). They both run together at slightly higher speeds/heat. The two 3-pin fans are co-joined by a simple wire "coupler" and are attached to the 4-pin CPU_OPT header. I can rationalize why it does what it does, and I can rationalize why it shouldn't be doing what it's doing! Please tell me the right answer, if you know! Cheers, Bill By the way, gigabyte included some fan and temperature software with their MB. Its doesn't work at advertised (where do the hours go?), but it can be made to work. |

Cheers, Bill By the way, gigabyte included some fan and temperature software with their MB. Its doesn't work at advertised (where do the hours go?), but it can be made to work. That's not what is shown here. I see two fans with separate four pin headers in this Newegg photo for the H105. I can't find a picture of the pump, but it would make sense for it to use a three pin. http://images17.newegg.com/is/image/newegg/35-181-060-Z04?$S640$ ( http://www.newegg.com/Product/Produc...82E16835181060 ) If a person wants to run fans in parallel, something must be done about the RPM signal. The RPM signals cannot be joined on the two fans. If I were to make an adapter cable, I'd either have to disconnect RPM on one fan, or run the RPM signal of one fan, to an "RPM only" connector to be run to some header that can measure the RPMs for me. FAN1 FAN2 +12V --------------X---------------X GND --------------X---------------X RPM --------------X PWM --------------X---------------X If I make an adapter cable like that, the 25KHz 5Vpp signal with variable pulse width (PWM), controls both fans at the same time. If the fans are a decent design, they should be within a 100 RPM or so of one another. The match won't be perfect (due to maybe friction differences or mechanical differences), but they should be in the same performance ballpark. In that diagram, only FAN1 has RPMs monitored, so you can see the RPM rate in Speedfan. I could make a two connector adapter, and route the RPM signal of the second fan, to a three pin connector. Just for monitoring and not for power. (My local electronics store (not RadioShack) has a small, poor selection of connectors and pins so I can make my own cables.) FAN1 FAN2 +12V --------------X---------------X GND --------------X---------------X (Yellow) RPM --------------X X----------------+ PWM --------------X---------------X | | +12V | GND | RPM -----------------------------------------------+ Now, speed control is on the four pin, via PWM. Power is drawn from that header too (so make sure the total fan load in milliamps, does not exceed the milliamp rating of the header. Both fans are commanded to do the same thing. The second connector allows the RPMs to be measured. You'll have to give me some idea what this "adapter" is doing, for me to figure out what is going on. My guess is, the second fan has radically wrong characteristics. PWM fans are supposed to have something like a two line response. When the control stays at 0 logic level permanently (0% PWM), the fan should still be running at a low speed. That's so your "low RPM" alarm doesn't go off unnecessarily. You would need a more complicated monitoring method (PWM, resulting RPM), to monitor the fans otherwise. RPM | / | / | / | / | ------- | +--------------- PWM % 0 100 As to what the Corsair fans actually do, you'll need to dig into some customer comments. I wouldn't leave it hiccuping like that, if it was my rig. I'd want to know "why". ******* I found the quick install guide. http://www.corsair.com/~/media/Corsa.../H105_QSG_.pdf On the one hand, the fan Y-cable, looks as expected. It matches my first diagram, with RPM on the second fan disconnected. That means, you cannot monitor RPM on the second fan that way. http://i58.tinypic.com/31788p3.gif You would need to adjust the response curve, so the PWM level doesn't drop so low, and allow the second fan to get in trouble. In my PWM fan behavior curve, what is supposed to happen, is the fan can't go below a regularly spinning level. There shouldn't be a "fits and spurts" level in the response. If the fan response curve was a single line at 45 degree angle, extending to 0% PWM input, then it's up to you, with your fan speed adjustment software and method, to prevent the PWM signal from dropping all the way to 0%. Maybe if the PWM signal stays at 30% say, the fans will be in a regularly spinning range. If it was my rig: 1) Pumps runs at constant speed. The three pin header for it likely doesn't have voltage adjustment in hardware anyway, so this should be easy to meet. Verify, using Speedfan, that the pump is in the right RPM range. If too high, there could be air in the liquid loop. If too low, it could be that the header isn't delivering +12V. 2) If I had the headers, I'd run the two fans separately. But that would complicate fan control. It isn't that common to have control software that couples two headers in terms of settings and makes them do the same thing. I expect that's why Corsair provided that Y cable. You can use the Y cable if you want, but just make sure the fan runs properly. What would really be nice, is fan control software that uses closed loop control. Where the RPM level was monitored, the PWM value adjusted, for a "level of cooling". And that "level of cooling" target was set by the temperature. That would eliminate all the concerns. Only if the software "hit the rails", and could not apply enough PWM to meet the target, then it would alarm and put a dialog on the screen saying something is wrong. The same sort of thing happens with your car. There is an acceptable control range, which varies as the car ages. But if some control loop goes out of bounds, maybe your car throws a code and "claims the oxygen sensor is bad". So cars are an example of well applied closed loop control, such that most of the time you don't have to worry about engine management. HTH, Paul |

Forgoing the control factors for speed or RPM monitoring. As it is, I've decent-sized to larger fans connected to the MB's fan output voltage provisions. Didn't used to, though. Used to splice and run them to the PS to make sure I couldn't possibly be stressing the MB. Just didn't seem right, at least to me, a masterworks of modern timing, to be driving some $5 Hong Kong fan on a special sale. Still don't care for variable speeds, especially (the lower the better);- temps, however, I am careful about. (Don't even care to go near what mechanics may say when addressing factory vehicle codes, those whom recommend the StealerShip as best situated to analyze and repair a modern vehicle. Not even with your 10'-pole barge pole. ...Defeats the whole purpose of a viable economic democracy, defacto, as one practicing competitive marketing, including aftermarkets.) |
