The Official PC building thread -3rd Edition

I like that statement, because it is clear, to the point, and completely understandable, provided one has a moderate Physics understanding

 

correct it is the fan that came on the heatsink in the amd cpu box ... ran down to count fan blades it has 7 blades... so I would need to procure a more bladed fan which might then fit snugly in the pump bracket slot

 

Oman7,
I would pull one fan header at a time and see what turns off in Everest. Just unplug and plug until you find it. I've seen weird fan speeds before with some no name fans. Did you see that 19000 rpm one I linked will? 40mm, that baby must scream!

Well I could draw a diagram and use arrows, but they would probably shoot them at me! LOL!!

Russ

 

19000Rpms is freakishly fast. I've never heard of anything quicker. That sucker must be unique in a way we've never read about LOL!

There's really nothing else that the 4383Rpm result could be. It has to be some miscommunication between the software and the board. I would bet money that if/when I remove the pump from the header, the high Rpms go with it Not sure where I have an adapter, but I can find a way. I think I have 2 adapters in use in the case. I'll make one of the components relinquish it for the pump

 

But it already shows the power supply occupied, so why would it read it at another location, especially at a different speed? That doesn't make any sense! I don't think unplugging the pump and powering it from the PSU will make it go away.

BTW, did you try the fan mod to lower the MB temp?

Russ

 

I haven't tried the fan mod yet.

Ok. I think I goofed. The 1200 reading is the Power supply. The scythe is ran directly to molex. I shall connect the scythe to the PWR_FAN, and give the pump its direct connection.
Give me roughly 20 minutes, then I'll post the result

 

Cool! Did you look at that fan? 40x40x28mm, 19000 rpm, 59.9dBA, 6.5 watts! I couldn't stay in the same room with that much noise!

 

LOL! I think my 1900 Scythe is pushing over 30dBA. Its pretty obnoxious. I can only imagine what that sucker sounds like. Probably like a blow dryer!!!
I'd like to manually control that scythe too. Probably software...but I won't hold my breathe...

 

What in God's Green Earth did you ever buy that beast for! That mother moves some serious air (110 cfm), but it also makes 37dBA doing it. I have a Zalman controller from my 9500. You're welcome to it, if you want it! You just have to connect two plugs. One from the MB header, and the other to the fan. You adjust it with a rheostat, right on the top of it. I only used it for about a week and then hooked the Zalman to the CPU controller on the MB! It just sat in the Cavalier case for a couple of years unused. I just tried it and it works fine. Nice solid controller though. You're more than welcome to it! Tune that baby down some and have peace and quiet!

Actually, I rarely run that pc anymore. I'll find a way. Much appreciated though Russ. I like a good challenge Fact of the matter is, I have very few 120mm fans. All of them are in use. And that pc requires one to stay cool. If I remove that 1900 scythe, things will heat up beyond "hells hot"! LOL! The 1200 scythe used to reside there. It's all good...
Here are the new readings. As you can see, disconnecting the pump, removed the high rpm error.

 

Just made a discovery. Saw that my CPU temps were higher than normal, and felt the back of the tower. Felt like the scythe wasn't running. IT WASN'T. I forgot to plug it in. I plugged it in while the PC was running. Not a practice I recommend mind you. But you see, the sensor cord(Yellow), was already plugged in. Its molex simply wasn't plugged in. The second I plugged it in, Everest's real time kicked in, and showed that I plugged in the Power Supply fan. Which of course it is not. Looks like another bug in their software. And the PSU IS running at 700. That sound better sam You were worried about it running at 1200...

 

No more 49C for the motherboard either, I see. 29/35 for the CPU and cores. I would imagine you should see about 43 for the CPU stressed with IBT! How did you get the MB temp down to 36? The error is probably the type of motor in it and gives false readings. Not all motors will give accurate results, but I'm puzzled as to why it was showing up different places with different rpms.

The motherboard temp is down, as long as I'm not stressing. If I stress, it shoots up The post above is at idle.

 

Do the fan mod and it will go away. I experienced the same problem. Mine got all the way to 53, and now the highest it's been in an 85F/29C room I deliberately let get that warm, is 40C. You can't hurt anything so try it. That MB temp was with the video card back in the 16x slot, too! If anything it will also help the Video card's temps a little bit as well. The fan will blow right on the back of the card! Damn near silent too!

Russ

 

I'll definitely be looking into putting a fan there. Shame I can't put that chipset in the liquid loop. Then I could really crank the overclock If the cpu is only hitting 42-44C, I have some decent headroom

 

To be fair, the 1900rpm slipstreams, when mounted somewhere relatively free from vibrations, are very quiet for what they do. They're not as loud as the FM121s were at the same speed I don't think.

 

You have to be kidding me! The 1900 rpm slipstream is 37dBA, the FN-121 is 700 rpm slower at 1200 rpm, and only 26.6 dBA. It actually shows as 24.5dBA in the Anechoic Chamber. Of course it doesn't move 110 cfm either, only 53.7! Then again, it had been in use for about a year before it was tested, but that shouldn't matter as it's not ball bearing

I would imagine if you lowered the fan speed on the Slipstream to 1200 rpm, it still wouldn't be quite as quiet as the FN-121. When I built this computer the FN-121 was the second quietest fan in the computer by a wide margin, next to the Kama Bay's 30 cfm, 800 rpm fan. Even then I was pretty sure that the 26.6dBA figure was a little high, as you just couldn't hear it from 2 feet away, powered by an external PSU. So smooth and vibration free too. Maybe I got one built on a Wednesday! LOL!!

Russ

 

FM, not FN.

 

Like I told 3kJodo, don't use the one from the 965. It's slightly thinner and doesn't move near as much air as the ones from the aluminum block coolers. The fan is a Foxconn, 9 blade and moves lots of air quietly. I'm going to have to move my Cooler Master fan back into the lower fan spot on the front of my case, as the Silverstone FN-121 doesn't have enough head pressure to cool the HDDs as good as the Cooler master did! UGH! That means I have to pull the HDD bay to do it. I may try the 40 cfm 800 rpm Scythe Slipstream in my Kama bay in place of the 30 cfm 800 rpm fan that came with it, while I'm at it. I'll be starting that new build for my friend up in Mass next week, so my new ODDs should be here, so I might as well do everything at the same time. At least I can ship it with the CPU cooler attached. I couldn't do that with the Freezer 7 for Gina, as the push pins would have broken. I'm also upgrading the memory in Oxi, as when Russell is playing AOE II, and all the armies are at full strength, it runs out of nmemory, as there's only 2x1GB of ram in it. I got a good deal on some GeIL black Dragon ram, 2x2GB for $86.
