@Al
for better using and controlling your machine use a cc_config as shown:

<cc_config>
<options>
<start_delay>120</start_delay>
<ncpus>48</ncpus>
<use_all_gpus>1</use_all_gpus>
<skip_cpu_benchmarks>1</skip_cpu_benchmarks>
</options>
</cc_config>

This way you can free some CPUs if needed for other work easily by setting ncpus to a new value.
I excluded the cpu Benchmark also.
The start delay is necessary to give Boinc enough time to find and setup all your GPU's

heinz, thanks for the sample cc_config, I'll make note of it when I get back upstairs to work on it later tonite. :-)


Keith, just spent 30 seconds Googling CoolIt, and found that they only OEM thru Corsair. But, it appears that they also make a higher end unit, the Hydro Seriesâ„¢ H110i GT Extreme Performance Liquid CPU Cooler. I guess I'll have to admit, I was swayed by the number, and failed to do proper due dilligence. Next time I'll know better, and the price is basically the same. Lesson learned, and hopefully I'll not have any issues with it even though it isn't a CoolIt built unit.

Yes, Red-Ray is the man. From reading the forums .... and official Corsair representative comments ..... I gather there is a bit of "not invented here" syndrome going on. Red-Ray has shown them their flaws and offered solutions, but they just ignore the suggestions. There's a list of ongoing flaws going back 3 years or so that are still in the faulty Corsair code in the forum.

Yes, Corsair just rebrands the AIO hardware. Asetek got into a patent pissing contest with every other maker of hardware and intimidated them into dropping out of the market or making major changes to the hardware to not make a patent infraction. CoolIt does mention their hardware on their website, then simply points you at Corsair for purchasing their product. The H-110(i) (GTX) etc. is CoolIt hardware. Ray explained that the superiority is in the electronic hardware and firmware controlling the cooler, not necessarily in the physical parts like the radiator, cold plate, pump and tubing. He can hook into a lot more of the control functions with the H-110GTX and the other CoolIt sourced product. For example, he can't control LED lighting in Asetek products, but can in CoolIt products.

If you look at [Status] > [Link Limits] in SIV64 you will find the matrix of Link devices. Look at the color blobs for all the AIO H coolers and match them up to the legend at the bottom of the panel. If you see a hot pink blob next to the device, that means Full Control of the device. That also matches up with CoolIt hardware.

There have been some early "teething" problems with the hardware from either source when new models have been released. That is sort of expected. After the products are mature, there have been very little issues in the longer view with both sourced brands. Normal "infant mortality" issues and some very few long term, many years in use failures, but really a very low percentage of total product. The mature AIO is a pretty much set and forget product.

I'm also referring to the radiator, pump, cold-plate and tubing hardware. Fans are another total thing. My stock Corsair SP-120L fans didn't last a month before their cheap sleeve bearings started rattling so loud it jostled the teeth out of my head. And spraying bearing oil out of them around the case. I replaced them last weekend with good Noctua NF-F12 PWM IPPC67 2000 rpm fans. Overkill for my use actually. I should have just bought the normal NF-F12A fans at half the cost. I've used them on my other two AIO coolers for over two years now with no issues. They provided better cooling at MUCH lesser fan noise. And with their bearing design they will last a lifetime.

Did a quick search on the fans you mentioned, you said that you bought NF-F12 PWM IPPC67 ones, but when I Googled it, it suggested the Noctua SSO2 Bearing, Retail Cooling NF-F12 iPPC 2000 IP67 PWM instead. Is this the one you meant to say, as there was only one result found which lead to a review of the 3000 rpm variant, where it says

Have you read the review of the NF-F12 IPPC-2000 PWM fan? If not, you really should. This fan continues onwards from where it stopped, and kicks it up a further two notches. So much so that you now have a NF-F12 with max RPM of 1500, 2000 and 3000. But unlike the 2000 RPM variant which comes in PWM, 3-pin and IPPC67 versions, you only get one version of this fan. At this speed, I dare say one is all you need. Thanks to Hank from Performance PCs, we now have the chance to take a look at the fan in detail.

Or, is it all the same thing and they just misspoke? You're correct, not inexpensive fans, but should last a very very long time.

Hi Al, no I got the naming wrong. You have it right. There are 2000 RPM and 3000 RPM variants of the Industrial spec Noctua NF-F12 fans. The IP67 certs are for dust and moisture intrusion. Definitely lifetime quality. What I found is that 2000 RPM was overkill in my usage. The normal NF-F12 1500 RPM variety is more than adequate. When I put the new fans in under my old speed control curve, they were running near the top of their rpm range and my radiator internal water temps were higher than before. Once I reduced the maximum rpm range down to 65% or 1200 rpm, then my temps fell back to the point where my temporary Noctua NF-S12 fans had the radiator. The iPPC fans push an ENORMOUS amount of air at incredible static pressure. I was defeating the heat exchange capabilities of the fin structure in my H-100iV2 30mm thick radiator. The iPPC fans would be a better fit to thicker radiators like my H-105 38mm thick radiators in my other crunchers. You can spend the extra $8 for the iPPC fans and get the benefit of lifetime fans at a very reduced noise footprint or just go with the normal 1500 rpm NF-F12 fans and run them closer to their normal 1500rpm spec. I am at 52° C. on my H-105 radiators fully loaded with SETI CPU and GPU tasks. The NF-F12 fans normally run somewhere between 900-1500 depending on workload and how hot the room is. A/C set at 78° F.

Al, I hope I haven't come off as some fanatic about Noctua fans. I just have very good luck with them and haven't seen the need to try anything else. Most of the negative comments about Noctua fans is the color scheme is offensive to many builders and they won't use them. I believe in "form follows function".

If you can find some old Gentle Typhoons, everyone always raved about them. I have also read very good things about the EK Vardar fans for use with radiators. Both of those not necessarily cheap either. You get quality for what you pay for in the marketplace. Google is your friend.

Oh heck no! I think they are the cats meow too, I have them (as well as their CPU coolers) on one of my dual Xeon rigs, it's an EVGA SR-2 running X5690's @ 3.47GHz, and the temps are averaging a very reasonable 50c, so no complaints there. I really don't mind spending a little more money on something that is such higher quality, because it's one less thing to go wrong, and it certainly won't be the weakest link in the system. It's not like it's a multi $100 difference, so I go with them whenever I buy fans. Sometimes there are higher rated fans in terms of airflow or maybe even noise, but when you add up all the things that they do well, overall they come out on top for me. I think I own about 25 of them between my Intel motherboard systems and my Xeon ones. The only systems I am not using them on are the Supermicro based ones, I am using their OEM cooling solution, and it works very well. I would certainly hope that they use high quality parts for their coolers, because these things are going into servers, and that is the last place you'd want to skimp.
