By the way has there been an announcement of when the H320 will be shipping?

inconsistencies in QA unfortunately.

Gabe and Bryan are working hard to rectify any issues, however.

I got exactly the same problem in two H220 units that Allygash is describing. Couple of pages back I post it blaming my cpu fan header. It is not in fact since on several motherboards (3 different ones) and 3 different PSU's I got exactly the same problem. I am in the process of RMA the pump/block second time now....

I am sure they are. I am going to ask a question out of pure curiosity, so I do NOT want a bunch of angry Swiftech afficionados jumping down my throat. Wouldn't it have been better to get the production and quality assurance issues worked out before the the shipping of the product? I realize that may take a little more time and money, but it spares the reputation of the company. I know Gabe is committed to correcting these issues and the customer service is superb. But nonetheless it would greatly reduce his and our anxiety if all major issues were resolved in the pre-market production process. This well may be how it is handled throughout the industry, but it then raises questions about industry practices. I guess that all goes into the equation of maximization of profits.
It would be ironic if the problem was caused by somebody scratching their crotch occasionally on the production line and some sweat getting on the pump components during assembly.

Here's my take on it, there are several factors that play out in QC/QA and on top of those the methodology used.

  1. Were the initial QA samples provided by the same production line as the retail product?
  2. How large was the sample size used in QA testing before going forward with the design?
  3. What was the duration of the initial QA and secondary QC testing of the retail units?
  4. What if any changes were made on the supply side after the initial QA engineering sample?
  5. How tight are the manufacturing tolerances compared to the initial engineering sample?

You did an excellent analysis of the issues to be resolved in improving the quality. I would think one out of every five should come off the line initially. Then after discovered issues are resolved one out of every 50. The issue of difference in tolerances from engineering and production samples is an interesting question. The testing on samples taken may NOT have been long enough in duration to discover the problem initially.

We're sending out your replacement pump today Gabriel. In looking into this the issue can't be related to the stress that the CPU is under. This pump wouldn't shut off simply because of heat load. These pumps can run at a much higher heat load than what a processor is able to generate. The issue has to be related to the pump periodically shutting off. The reason it's only being noticed during load is because this is when it gets hot enough to cause the system to shut down. During idle the processor isn't under stress and therefore is less likely to generate the amount of heat necessary to trigger a shut down. Being also that it starts right up again, by the time it starts back up the processor doesn't have a chance to reach the critical thermal threshold while at idle. I hope this clears up the questions concerning this issue.

If you have your pump connected to the Chassis 2 header then this is could be the cause of your issue with our pump. The Chassis 2 header is most likely voltage regulated and therefore it's not giving the pump the PWM signal that it requires for proper functioning. Please try using your CPU fan header to see if that corrects your issue with our pump.

Yes we do. You'll need to go through Bacata to get RMA support for our products in the EU.
