There is a loud noise coming from my chassis this morning, found out it was the pump of H70. The CPU temp seems to be normal though. Will contact Corsair or seller:mad:

update1 09/2010: the vendor told me they have sent the H70 to Corsair.
update2 01/11/2010: 2 month later, 28th October, the vendor told me that Corsair have replied. Corsair examined the H70 and would like to provide a replacement or full refund. I chose the refund. They didn't give me an explaination what went wrong though.

you could use a little cable management, but other than that, sorry you had a bad experience with the H70. This is the first failed unit I am hearing of.
 
Good luck. In my experience Corsair's tech support is slow as molasses.

Also love that your front intake is completely blocked by cables. :p Though it looks like there's not much room left in that case so I understand the laziness. Routing behind the motherboard and back panel sucks.
 
You do know that you have the pump/cpu block at the highest point right? If there's any amount of air in the there, the pump will make strange sounds because it's not pushing anything for that split second.

If you put it in the exhaust at least it would close to level.

This definately can be the issue, or an issue.

Like most pump operates, it wise to have water flowing into the pump by gravity, then the pump will operate as normal, and will flow water out as usual. Basic principal, try putting any pump above water and see if it will suck up water. -=P (it wont) It will just keep operating, but no water for it to push. Try placing that radiator at least mid point to the cpu block. See if that changes anything. If not, its probably a dead pump by now. (unless its a magnetic pump). Any pump will get loud with its not operating with water, water will help dampens the noise. Hence, might be your reason here.

(only exemptions, above water pump will be otherwise, tho these are completely sealed with a pressure 1 way valve, for example only BIG water well pump, but thats irrelevant to this)
 
Yeah, I just caught that. Do you have your H70 mounted at the top of your case, or am I seeing things.

the problem is getting it to fit on that fan mount, if I remember right, it's a 80-95mm fan there. I know they make adapters, but I think things get a lil' cramped with that mounting option in that area for the h70.
 
An option could be to some slight modding in which you mount the radiator on the back of the case or on top(not sure if it would fit up there).

Cut a piece big enough to get the pump through, slide it in, cut some holes for the tubing and reattach the piece you cut out. It will unfortunately make it a little louder. Without the adapter I'm not sure what other option you have. The way you have it setup is the most unideal way. I really like the look of your case, but damn it's cramped and looks like it lacks some cable management (get on that man!:p).
 
I totaly agree with you guys about the cable... Just don't have time to sort them out.

Other ppl have done the same for H50 in the same chassis, haven't heard simillar problems. Maybe the extreme tension of shortened H70 loop compare to H50 caused the problem

@BillParrish, I have lay the machine on the floor last night, it still gives the loud noise this morning, I will send it back tomorrow
 
I would return the H50 too. It's definitely broken. I would mount it in the rear exhaust next time though.
 
The way you have it in your case is all wrong.. you're putting extra stress on your pump. Your pump shouldnt be the lowest point in your loop..
 
no the pump as water is heavier than air and will goto the highest point in the loop always.

I don't think you know what a H50/H70 is. The lowest part is the radiator. The pump is at the CPU, which is the highest point
 
The radiator should level or above the cpu/pump PERIOD. The pump will ALWAYS have to be primed by the gravitation of water from a radiator thats naturally spilling water into the pump. Do you get the concept?

Try putting a pump ABOVE water and see if it will suck up water? Then try to put it BELOW water level, see what it does. Got it? Basic concept...
 
Call Corsair and ask them for an advanced replacement

their RMA dept is really easy to deal with

you don't have to repeat the basics, it's just not possible to mount the radiator higher than pump in the NZXT Vulcan.

anyway, there shouldn't be any air inside the H70 loop, at least not within 2 weeks.

You can tilt the case so that the pump is on top or lie it down. A case is movable, therefore any initial loop orientation is limited only by the imagination.
 
Wow, it took that long for them to come back to you with an answer? That sucks.

Also about air in the loop. "Integrated pump and reservoir is sealed for zero maintenance and improved leakage protection." So it being mounted properly and "maintenance free", air in the loop after 2 weeks is out of the question, Corsair failed here.
