Resit your ram and possibly cpu. If it persists, id rma the mobo 1st. But i personally never heard a pc do that kinda sound. Are you using a soundcard or inbuild audio on your mobo?
I have yet to run the mem test over night but might give it a go in the next couple days. It still does this every once and a while. Just defended my undergrad thesis today so I have a bit more time on my hands now. @ Doxy The sound is onboard and the speakers are Logitech Z-5 USB speakers. PC Updates: A long while ago I decided that I wanted to increase the airflow in my case. To do this I was going to replace the bottom and rear intake/exhaust fans with much higher power fans and use them both as an intake. The H100 and positive pressure in the case would force the air out of the case. I settled on some monster fans (Triebwerk TK-123) that I thought could be tamed. The problem with these fans is that they are 1.5 Amp fans and the mobo headers can't handle anything over 1 Amp so I needed a fan controller if I wanted to slow these guys down. I settled on the corsair link. Turns out that the link is actually a POS and gigantic waste of money. The thing they don't advertise is that it doesn't work with most fans on the market. Up until recently it didn't even work properly with their own fans. Along with the compatibility issues the software is junk; stay as far away from this thing as possible. Since the link utterly failed at controlling the fans I decided to physically alter the power delivered to these fans. Here is where resistors come in. I did some calculations and found that in order to drop the RPM of the fan down and achieve a bearable noise level I needed a 10W 12 Ohm resistor. So, I grabbed a 3-pin fan extension cable and soldered in the resistor. Voila! drop in RPM to ~1800. But!!!! I couldn't control the RPM on the fans at all. They were stuck at 1800 RPM and wouldn't quiet down any more if I wanted just an idle profile. The fans were much better however I blew the circuitry in the link cooling node (I might have caused a short by touching the wire to the case by accident, not sure. I hadn't heat shrinked wrapped them as I was still testing) :/ :/ So today I finally got the replacement cooling node and gave it another shot and they ran through the node but still no control. I have sadly decided to remove the fans from the case completely and will take out the corsair link entirely I really liked the looks of the fans and the airflow of these things was astounding. Corsair Link Commander Installed All wires hidden Cooling node behind mobo tray Triebwerk TK-123 Triebwerk tk-123 + 120 to 140 mm adaptor Triebwerk TK-123 fan installed in bottom of case Resistor Soldered in to drop voltage Video of Triebwerk TK-123 I came across some new fans today that I hope will work with the mobo. They are PWM fans that should be able to be controlled by the fan headers on the mobo and the thermal radar that comes with the sabertooth z77. The fans are the silverstone FHP-141. It looks like they are made to give a wide range of control 500-2000 RPM via PWM. I placed the order with NCIX tonight so hopefully I will get them by next monday/tuesday. The PC is still sitting on my dining room table because I haven't felt that it is complete yet. I think after this and sorting out the noise problems I can be content. Silverstone FHP-141 140mm PWM fan
I am still of the opinion it is either instability in the RAM or maybe the CPU's memory controller. The only times I have ever heard that sort of noise is with memory related problems.
I have actually always heard that negative pressure inside the case is better than positive. Proper cooling design has always been 1 good performance intake with 2 exhaust fans. The negative pressure helps keep the inside cooler. Positive air pressure will let heat build up more.
Makes sense I suppose. There shouldn't be a whole lot of stagnant air in the case with how the airflow in the case will work out. The rear intake would force air directly over the mobo power delivery system, RAM, socket as well as some on the topside of the video card. The H100 will exhaust air out of the case and the bottom intake has a clear path straight through to the vents at the top of the case. I have read that positive pressure will keep a tidier case so that is what I was going for as well as moving some more air over parts of the mobo that get a little warmer. The only area I have concern for is the space underneath the video card. There isn't a whole lot of circulation there aside from what is under the thermal armour from the 45mm fans. The PCIE, USB, and SATA controllers can get pretty toasty under there.
See what you should do is use two of those fans as intake, and then stack FOUR of them on the H100 as exhaust And before you think about it too long, yes it is possible. My H100 has four fans, just not as crazy as the ones you bought. I used to only use fans like that back in the day, but Ive eased up on how hard I push computers now days and am content with regular old 1800rpm fans with at least 70cfm.
I would have to mount two inside of the case pushing air out and two outside of the case on top of the holes as pull would be madness. Not quite as crazy as the 12 delta fans :S They would likely sound as loud though at max rpm!
lol. If I continued on the same course for computers as I had been 2 years ago then that video would be my cooling system today. Even back then I used to run 6 of those same delta 200cfm fans. Also, I accidently cut myself once cause I used to stick my hands in and change stuff while the computer was on. Once my finger got caught in the fans and cut through the skin. Blood flew around a bit and I ended up losing the motherboard from a short due to the blood. I loved that board...
HAHAHA that is one of the funniest stories I have heard about how a part was wrecked I've picked up those fans many a time while they are running and I am always nervous doing it. Those fans are supposed to be 215 CFM at 3000 RPM :S I'm actually quite sad I couldn't use those fans, they looked bad ass. The company makes less intense fans I would love to get that would be compatible with the mobo but I don't know if they are able to be controlled that way maybe if the silvertones don't work I'll give them a shot.
On my H100 I am using it to run four Scyth Slipstream's that run 1900rpm. Model is: SY1225SL12SH. I know not the same as your big boys, but they all run fine through the Corsair built in plug on the H100. I chose them because their are both high airflow and still somewhat quiet. http://www.scythe-usa.com/product/acc/026/sy1225sl_detail.html Scythe USA is closed though, or will be soon.
It's funny, I only ever read about the gentle typhoons yet as far as specs go those appear to be superior. I wonder how they compare in the static pressure department. How are they as far as noise level + cooling goes compared to the stock h100 fans? The H100 is fucking awesome but I'm not thrilled with it being the loudest component in my system.
I am not sure how they are compared to stock since I never used the fans the H100 comes with. Check out how they compare to others here:
So the fans were delivered today and I am pretty happy with them so far. My one complaint is that they are 140mm fans with 120mm mounting holes. Not a problem for the rear intake but the bottom intake only has 140mm holes :/ I will likely be drilling some of my own 120mm holes so I can install them. They are controlled perfectly via thermal radar. No annoying clicking as with the corsair SP fans and they can be completely shut off via thermal radar if the temps aren't high enough. I'll likely have them set to stay off below 30C. They also come with plastic pegs to install them with instead of using screws. To help visualize airflow, here is a pic I came across that someone else made. Fan:
I got the fan holes drilled today for the 120mm fan mounts. Needed: -Pencil -Thin piece of wood for a template -Nuts and bolts to hold template in place -Drill+(drill press, makes drilling the template quicker) -3/16 drill bit -Irwin Unibit #1 -vacuum to clean up aluminium shavings I started the process by taking this thin piece of wood and marking holes from the rear fan mounts onto this with pencil. After marking all the holes I used the 3/16 drill bit to make the holes. The nuts and bolts were used to fasten the template to the existing 140mm fan mounts on the bottom intake. After the template was mounted I used the 3/16 drill bit to start the holes so I would lessen my chance of having the bit wander off when I used the step bit. On the left is the first hole drilled and on the right you can see where I started the hole with the 3/16 bit. All 4 holes drilled with pretty clean edges on the top side (small amount of burs on the bottom as expected). As you can see the drill wandered a bit on the top right hole. I didn't have enough pressure on the drill initially since it was in an odd location. The holes were drilled to the 7/32 step on the bit. Final picture of the fan installed with the vibration dampers The total time was about 20-30 minutes I would guess. I was pretty nervous about drilling holes in an expensive case but all turned out well. Couldn't be happier with the fans and I have completely given up on the corsair link software. I implore anyone contemplating this software not to waste their money on it and buy an ASUS board with thermal radar or fan expert. That is unless you need to control fans that are rated at a higher amperage than the mobo headers can handle.
I have to RMA my HX1050 now :/ God fucking damnit. RMAs/exchanges on PC thus far: 4x Corsair K90 keyboard 1x Corsair Link 1x Corsair HX1050 PSU
Good thing I bought 4 Scythe ap-15s. They are going out of business? Also, using the back fan as intake is ok just remember it might be in taking the heat from the gfx card.
Indeed, my only problem now is that I have to send the fucking thing back and most likely pay for shipping. I will call CS and see if I can get them to pony up. If not, depending onw how much shipping is, I may just get a new non corsair PSU so I don't have to deal with them anymore. Getting sick of shitty products. I don't get why so many people want to suck their dick. >.< It can't just be coincidence that all 3 things that failed in my system were corsair. Not out of business, just stopping distribution in NA. Not sure why. You will still be able to get from over seas. I don't think it will be a huge problem. The GPU doesn't put out nearly as much as the fan sucks in. I have a sneaking suspicion that the pc would be totally fine with only an intake in the bottom and the H100 exhausting out the top. There was quite a while where I didn't have either of the intakes installed and my temps weren't crazy. It helps that it is currently winter though.
Corsair doesnt even make their PSU's though, so thats probably just bad luck. Most of their power supplies are made by Seasonic if I remember right
