Description

Just finished my new gaming rig. Lovely machine, all works a treat. However I do have one question and a potential problem.

The CPU makes a buzz. A little like an HDD trying to read the disk. Like electrical static. It's coming from behind the pump for the H90 (or could be the pump itself? I doubt it?) So it's either the CPU or maybe a transistor located near the CPU.

I'm not sure if this is bad, or normal, or if I should just leave it alone. I never noticed the noise before I started my tame OCing. I'm completely new to OCing, I've never done it before but after several articles and a few videos, I bumped the CPU up to 4.4ghz. I went higher eventually to 4.6ghz but was unhappy pushing 1.3V through the CPU so lowered it back to 1.2V and 4.4ghz. When I discovered the noise I had done my first overclock and was unsure as to whether it was there before. I have reset the BIOS settings back to stock and the noise is still there.

I hope there is nothing wrong and this is quite normal. You cant hear it with the case together unless you put your ear up to one of the grills. So you get an idea of dB. :)

it is recommended to mount the radiator higher than the pump.

The idea is to mount the reservoir higher than the pump.

Otherwise, with your pump sitting higher than your reservoir, any evaporation of the fluid will allow air bubbles to move up towards your pump. This just means that you'll have issues with bubbles getting caught in your pump from time to time, which will result in clicking noises in the pump.

2 things: 1) Why is your GPU located at the bottom of the motherboard? I suggest moving it to the top. 2)Are those molex to 6 pin connectors? I'm pretty sure the TX650M comes with PCI-E 6+2 pins.

Thanks for the feedback. The cables comin out of the GPU are the 2 that were supplied with the card. The card is at the bottom because the mobo has a fancy heatsink at the top. This prevents me from mounting the radiator and fan at the top as there is no room. The pipes for the cooler run across the path where the first PCI-E slot is and you can't fit the card in because of it. Is it bad having at the bottom? Performance wise?

those cables are provided if you need the adapters, you'd get a cleaner look and more reliable power from the dedicated pci-e rails rather than the molex.

i'm not understanding why you can't mount the radiator on the back of the case though. if the radiator is pushing air towards the front, you are denying the gpu of airflow, and if it's pulling air towards the back, then you are providing pre-heated air to the gpu, raising it's ambient temps. i would try to get the radiator mounted somewhere above the gpu if at all possible

they only supply the cables incase you need them? i used the ones that came with my 760 because there were instructions that said to do so. i should probably switch mine too then?

if your power supply has the two pci-e cables, then no, do not use the adapters they provided

on all Intel Z87 motherboards, the second PCI-E slot is only wired for x8 bandwidth, and also causes the top slot to be wired for x8 bandwidth if the second slot is occupied; however, moving it to the top dedicates all 16 PCI-E lanes to the card occupying that slot. technically, it doesn't matter much in terms of performance (PCI-E 3.0 @x8 is theoretically the same speed as PCI-E 2.0 @x16), but it's always considered good practice to put the GPU in the top slot anyways.

I could potentially put the card in the top slot, I'd need to drill more holes through the mounting bracket for the fan at the bottom to accommodate 140mm. I still don't think there'll be room, but when I have some free time ill give it a go. I'd rather have the GPU in the first slot.

couldn't you have placed the H60 at the rear, where the 120mm case fan is? i don't think those mosfet heatsinks would be an issue with mounting it. you could orient the hoses closer to the top of the case, thus eliminating the problem of routing them over the first PCI-E slot, and simply leave the H60 in pull configuration.

Aside from what others have said, how is that Nanoxia case in terms of noise/cooling? Any airflow issues?

I was itching to buy one some time ago, but moving to the US made acquiring one difficult.

Is the heat from the OC'd CPU going back inside the case? If so, all that heat must be heating up that video card.

Coolers are advised to be intakes so yes the heat would be going back inside the case. However the air coming from behind the radiator doesn't seem much warmer than directly from an intake. Ill keep an eye on GPU temps though in case.

I dont know... When I start doing heavy processing on my amd 955 OC to 3.6 (liquid cooled), that thing turns into a heater core. I have the radiator as an exhaust with a push/pull system.

Coolers are advised to be intakes but some of them have to be exhausts so that the fans can work efficiently

Personally, I would mount the radiator in the roof, exhausting up. If you're running your CPU at 70 degrees for maybe more than an hour, the liquid will get hot enough for you to feel it. I have an H100 that runs around 70 degrees at 100% load (@ 4.8 with prime95) and it is noticeably hot.

Mounting it in the roof also lets you move the GPU to the top slot.

Try rotating your CPU cooler block 90 degrees to your right (so the tube connectors are facing the front of the case), I would bet that gives your more room to move your GPU to the top slot. Another option would be to get some fans to put on the top of your case and run the back of the case exhaust fan in pull with the radiator mounted there. Personally, on my Rig I run my closed loop as an exhaust with a push pull fan setup and get as good of temps. (I'm gonna post my rig this weekend now that I've finally finished my case mods and desk to go with it.)

Move the rad to the back vent, and move the GPU to the top slot. The rad is meant to exhaust out the back to keep the temps down.

Change the molex to PCIE adapters and just plug in the PCIE cables to your GPU. It is dangerous to use those on your video card. Things can burn. I don't even know why they include them.
