MCP355 making squaling noise but not pumpming the water

[TurK-FX]

hi guys,

i put my loop together,
My system is
I7 920 D0 with D-tek fusuion V2
Rampage 2 extreme with koolance nb/sb block
2x bfg GTX280 H2OC edition with dd gtx280 block
Thermochill PA120.3
Thermochill PA120.2
Dual Heatercore with custom shroud
DD dual bay Reservoir

the pump is enough for it or cant handle this loop all alone?

I had this happen to me once. I couldn't figure it out, but eventually I noticed it was pulling air from my t-line (next to the pump inlet) and killing itself, so I filled the t-line and capped it. It should handle all of that, but I don't know how restrictive the DangerDen GTX280 blocks are. The Fusion v2 is a little restrictive, and FC GPU blocks usually are as well, but the Thermochills are very low restriction. Don't know about the Koolance block or the heatercore. You should be okay with flow rate, especially if you have a XSPC top, but you might be straining the pump a little bit. I would suggest splitting it into two loops. Your pump just might be dead. Check the inlet.

pump is brand new but, i used it only 10-20 hours. But i left it like that a few hours. Still when i turn it on it is making noise like working but it is not pulling the water. i dont have t line i filled almost a 3quart coolant i turned it over to make the water flow. i am thinking to put second pump. i cant do 2 loop due to limited space for reservoir. how about one big loop with 2 pumps 1 reservoir?

i need a picture.

im guessing you have somthing lose and itss pulling air into your system so its not getting bleed.

i added 3 pics, let me know if you see any problem.

i think you have common bleeding issues.

All your ups and downs, and the fact you have a bay res, and its hard to keep topp'd off.

From what i can see, it looks like your going res to rad to pump. That can cause bleeding problems, try rerouting it to res b4 pump, so water can reach your pump easier.

 

[PCTC2]

It doesn't look like any water is at the pump at all in those pictures. If you run a pump dry at all, you risk killing it, or at least damaging it.

Looking at the photos, Aigo and PCTC2 are right.

You are using UV dyed liquid in the loop and it looks as if quite a few of the tubes are empty / partially filled. Where theres no liquid, there's air and you have a helluva lot of air in that loop.

As PCTC2 said, if you have been running the pump 'dry' then the pump will be either damaged or at worse, dead.

Edit: Your loop must be completely full of liquid, not partially

thnks guys, being noob caused this 🙂

i will put the res before pump. Hopefully it is not dead yet. It is brand new pump

if it isn't dead, you may have severely shortened it's life. I'd replace it or get a spare in case.

i have mcp655 spare, i think i am just gonna use mcp 655 and keep this one spare.

I don't think they are very restrictive. Typically the DD graphics full blocks just have some small fins in them and basically just let the water through the block in somewhat of a "U" shape with the fins parallel to water flow.

nah dont worry.

the impeller and bearings on the 355 is very durable.

As long as you didnt have it on for hours and hours.

Which i hope by doing this you made the impeller have some coolant. Looks like your also using hydrx, or some antifreeze, so it should of lube'd your chamber and kept it somewhat safe.

Yes i use antifreeze.

I got it sorted. Now flowing like a crazy river. pump is working well.
Only problem i got is that i broke the plastic barbs of the heatercore. I installed mcr220qp instead of heater core. it wont perform as good as heatercore but i am hoping to hit at least 4.5ghz with my I7 920 D0. Tonite i will do the cable management and rund it 24 to see if there is a leak. and i will start using it tomorrow.
