The Official PC building thread -3rd Edition

Sam,
Given the blade design, it's entirely possible that the specs are at least reasonably close to correct. From an engineering viewpoint, the larger outlet of a 200mm fan won't feel like 110cfm at all, because of the larger area the air has to move through. Move 110cfm with a 120mm fan and you will feel more air flowing, but it would be fairly loud. An 80mm moving that much air would be unbearably noisy (I know, I have one), but would make the drapes move from about a foot away. The feel, is all about how fast the air coming out of the fan dissipates. The larger the fan, the shorter the distance it takes to dissipate the airflow exhausting the computer. At 700 rpm they should be very quiet!

I'm going to give you your laugh for the day, complete with my red face! My computer crashed last night while running ConvertX. I just shut it down because I wanted to go to bed. I looked in the setup this afternoon and discovered a mistake that I had made. For some reason the adjustment for the CPU NB VID control is backwards from all of the other voltages. As I was carefully checking my settings, I happened to notice that the voltage was -.025v, not Plus! When I hit the + sign, it went down to -.050. It's now set properly to +.025v, and now, it runs like a dream!. All the different times I've been in the setup, I never noticed the reversed +/- keys for that one setting! I've seen that in other settings on many motherboards before, just not one of the voltages! I've also been able to get the memory to run on the 800MHz Boot Strap. For that I'm awarding my self "The Dumb-A$$ of the Month" Award, for missing that one!

I'm still fine tuning, but I have it running at 3.5GHz with a CPU Host speed of 250MHz, using the x4.00 multiplier and the memory is running at 1000MHz. I'm only going up 2MHz at a time now, because a 2 MHz increase in host speed increases the CPU 28MHz. As long as I don't exceed 1065MHz on the memory, it will run with the x4.00 memory setting! If I go past 1065, the multiplier has to be set to x3.33 (667MHz), and the memory would only be running at 832MHz! I guess you're never too old to learn!

Best Regards,
Russ

 

The SilentPro seems a nice unit, It's far from as silent as the best of them, but it can hold its own against the Corsairs. Of course, the review quoted isn't using anywhere near the sort of load the unit is designed for.

I'm not entirely sure what the guy means about Corsair being a tier 2 brand though

 

well i was almost dead set on getting the silent pro until i read that review about the cables being snug in his HAF922. plus another review said something along hte lines as the 12v rail isnt useing the correct 12v's it is actually 12.57v. so its over volting. he said it messed his system up... not that i think he might not know what he is doing but im sure its more than i know. so that does have me worried. but it is under warranty. a 5 year warranty. but the corsair does have a 7 year warranty. and its cables work just fine in a cosmos s full tower so i doubt there will be a issue with cables there.??? well i have about another 12 hrs to make up my mind..lol

ok everyone cast their vote for which one of the 2 i should get and i will go with the majority. seriously.....!!!!

 

the HX650W

Cons

Wires aren't as flexible as claimed.
Would have preferred individual
connectors for each device.
Cheap wires and connectors.

Overload Protection: No

silent pro

silent operation with intelligent 135mm fan speed control, Flat cable design for easier cable arrangement

Overload Protection Yes

this is the review from the guy with the issues and talks about the overload protection.

Pros: None.

Cons: This PSU has damaged my system.

The voltages are outside the tolerance ranges of the components.

Example: 12V is 12.57V.

The motherboard, system memory, GPU and CPU have all been subjected to significant over-voltages. The GPU is damaged (wavy/moving display artifacts) . I am evaluating the other components, which, if not showing damage now, will definitely do so later.

On 1/31/2010 CoolerMaster would not affirm that the PSU was defective. They stated that the PSU could be responsible for the over-voltages, but that additional testing would be required to insure the problem wasn't coming from another component.

Other things I learned:

The ActivePFC on this PSU is simply for auto-sensing 110V-220V electrical systems, not for controlling power flunctuations, as I had assumed.

Over-voltage protection is a feature of ActivePFC, so, again, not defective.

You should never scrimp on the PSU. I didn't realize I was.
Buy a better unit.

I am going to Silverston


to me he sounds like a disgrunteld ups worker.(no offence OM7).lol but what he says make logical sense.
but im not looking at that as a deturent cause every now and then you get a bad part. doesnt mean they all are bad. my concern is if the cables are long enough to go up the back of the mobo tray to plug into the cpu power???

look at the cables for each of these and look close. they look the dang same to me..??

 

That's exactly it, the larger a fan is, the more air it can push at the same blade velocity due to the increased area of airflow. To get 100CFM with 100cm^2 as opposed to 200cm^2 means the air comes out much more forcefully, creating both more turbulence noise, and also more tonal noise since the blades need to be spinning at a higher rpm.
However, there is another issue at play here. 200mm+ fans use an enormous amount of current. This means that in order to be able to be powered off motherboard headers, they need to be low speed, or they would exceed the maximum current. That seems to be why you don't see high speed 200mm fans in cases. Annoying as they could be really handy.
Running a fan at a low rpm decreases efficiency. Not only that, but for some reason large fans typically come with very thin blades. This cuts down on airflow substantially.

Rob: Overvolting is common with cheaper high-grade units like the Coolermaster SilentPro, the Toughpower was something like 12.5V too. It's not a problem, it's within spec for ATX guidelines. If something messed up at that voltage, it would have anyway. That's what regulation is for. You don't see the 12V output on a PSU upping to 13V when the mains voltage is 8% higher for the day (it can happen, UK spec should be 230V, but we regularly get 247V here) - same principle applies with a PSU.
I vote Corsair, because it's more proven, and not any more expensive.

Will: Those specs listed are wrong. Of course, the Corsair has overload protection, it's a mandatory safety feature in all PSUs.

 

score
Corsair 1
collermaster 1

 

Hmm, Stiff cables. Not that much of a downside really
I'd ideally like to see an acoustic benchmark of the new Corsair units to see if they're on a par with the old ones, or hopefully better.

 

On my UD3P and I45 I had to use a adapter plug on both boards even thought they was in the same case my CM590, Robo. I would say the other cables to your hard drives and odd's will be far enough long to reach and yes the cables are similar in design but how about in Quality?

I Vote CM 700 Hands down no problems the with power here on my UD3P, or my Ati HD 5770 or the Q9550 at 3935Ghz Oc'd sense November

 

ATX 8-pin extension cables are pretty much mandatory in full tower bottom-mount PSU cases nowadays, I have to employ them in both the HAF932 and the NZXT Whisper.

 

yes . I had to use on both boards in this 1 case on 2 different psu's the OCz and this CM...Rob gonna have to get 1 anyway

Rob,
If you don't know which one to buy, knowing all of that, I'm going to give "You" my Award from my last post! ROFLMSOAOTIC!

Where's the LG ODD?? I'm disappointed in giving you some advice and you don't take it... hehehee.

NICE setup Robert!!! Both of them.

 

tbh and dont laugh, i thought i clicked on the lg drive you linked me to and hit add to cart. didnt look at it until i hit the buy button. iwanted to get one im not worried about it not scanning i have enough that can do that. but like i said they are cheap enough and i do want newer drives in my main rig so in a week maybe ill order one of the LG's and a lite-on and have a LG,Lite-on, and Sony in here

 

Personally a user of Lite-On. I dunno if it's just me or what but the few LG drives I have used felt like they were made of the cheapest plastic possible...

 

oh im a lite-on fan boy myself dont get me wrong..lol but ive had damn good results from the optraics that i have now would say they burn just as good as the liteons. and the LG that GM linked me ive heard alot of good things about it as well. heck for under $30 if something does go south its easier to handle.lol

 

It is of course completely irrelevant to the quality of the drive itself but Liteons and Optiarcs are definitely made of cheaper plastic than the LGs. The LG drives feel quite solid by comparison.
