The Official PC building thread -3rd Edition

For triple rads I think 1400-1800rpm is just about the sweet spot for performance/noise. Higher and lower rpm will have a noticeable effect but for most rads anything past 1800rpm gains very little. Exception being the HWL rads which seem to really need high rpm fans (minimum 1400rpm) to even function.

The six 1850rpm fans on my rad make more noise than I anticipated although on a quiet morning it's still nothing but a slight hum from the far side of my desk. Based off what one of them sounded like by itself I think what I might be hearing mostly is the air moving through the rad, can't be sure though as I've heard neither a rad with fans or six 1850 rpm fans before.

Edit: Just took a quick look and it seems single rads respond almost linearly to rpm's so it mostly comes down to the noise/performance one wants.

 

Will,
You might want to include an ambient temperature with that information, since I know that you keep your home quite chilly. Otherwise people might not realize that you run your computer in a 73F/23C environment, which is a much cooler environment than I usually see here in SoCal this time of year. Not being picky, but your room temperature can make all the difference in the world, as to the temperatures you see on your computer. I rarely get to see room temps below 78F/26C, this time of year. Normally in the summer months it's between 80F to 85F in here, with outside temps between 95F and 110F. We had such a cold spring, that I have no idea of how hot to expect things this summer. It's really strange to see the shadow of the house next door, on the south side of my house, as we've never seen that before, at least not in the 5 years I've lived here. We've only seen 6 days above 80 and 2 days above 90, the entire year, so far! I recorded these temps at 80F/23C, last week.



Since I got all my fans straightened out, the CPU temp has not risen to over 48C to date, when stress testing, and with stressful apps like DVDRB/CCE it hasn't gone over 43C yet. My video card has been moved back to the proper slot, and everything seems to be working like a well oiled machine. I think I'm ready to face the summer heat, if it ever gets here! LOL!!

Red_Maw,
A lot of the noise level has to do with the blade design of the fan. The fan that came with the Coolit ECO is much quieter than I expected it to be. It also helps that the "Push" fan has a lower CFM than the "Pull" fan. No rocket science here, but the same basic idea as a turbine in a jet engine compressor stage, in that you want the airflow to expand and build as it goes through the radiator. It makes the 1200 rpm Scythe spin about 1400 rpm without a lot of noise, doing it. Switch the two fans around, and it get's pretty noisy and less efficient! I've tried several different fan combination's, and so far, how I have it with the Scythe pulling and the Coolit stock fan pushing seems to work best.

I'm currently working the design of a miniature air turbine for dental handpieces, based on the same principle, that moves the largest rotational mass, closer to the end of the drill bit (Bur), so there is less deflection of the rotational mass to reduce bur whip, and increased torque without having to increase the rpm's to do it!

Best Regards,
Russ

 

Wish I knew that before purchasing the fans If I get a second rad I'll buy some 1400rpm GT's to use as pushers; live and learn I guess.

 

i wonder why we haev a cooling thread stickied

 

Conversations digress, it happens

 

It all has to do with building. We pretty much cover all the components here, at one time or another.

without a doubt. i was just joking, i love reading it, as cooling isnt my strongest point. as long as it isnt greensman drumming on about DVD drives im content

 

Shaff ...I'm interested in an SSD Drive. But know nothing about them. What I want to do is put my Operateing system and about 4 Gigs Software. What I need to know is what SSD Card I need and what size would you recommend
I was told some cards are not Bootable

 

well first thing is first, what budget do you have to work with?

 

As far as SSD's go, pick one with a larger capacity than 30GB. After using an SSD for nearly a year thats my only gripe, wishing i bought bigger.

 

Shaff...$100.00

 

$100 really isn't enough to get yourself a good SSD, and the bad ones are very bad indeed.
The cheapest one I would ever recommend is this:

But really, the one to buy is this one:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820167023

 

Give me a suggestion as to my first post
SSD for Operating system and 4gig software
Size not price

Um, see above? the $120 X25-V is 40GB, which is enough to fit an OS and a few gigs of programs, but it has a slow write speed. Otherwise it's fine. The X25-M is the full performance version, and it's $80 gig, but obviously, is far far more than $100. I would always recommend Intel SSDs due to their random data performance being so much better than almost all of the competition - it is random data performance that really makes an SSD feel like an SSD.

 

OK THANKS, Guess I'll wait

 

I see the 80Gb version has dropped in price significantly! Highly tempting to get a couple. 160Gb is not enough for me though. I would prefer at least twice that. Guess I wait too. Good to see the prices dropping though I'll be raiding a few of those in no time!

 

Depends on how the games are coded. If they use huge piles of small files, or worse, piles of small files compressed into a large archive, using an SSD will be beneficial. Otherwise, the read rate of a high-end hard drive will more than keep up. A lot of game loading time is down to the CPU, not so much the hard disk (within reason). Other than game and software loading times, I see no reason to be using an SSD over mechanical drives other than noise, and replacing terabytes of storage with SSDs, not going to happen for a good few years yet!

 

LOL! Yah, I won't even dream about Terabyte SSD drives. I saw one on newegg a while back. It was extremely expensive. Quite the bummer. But understandable. I won't even begin to hope at present

 

Oman7,
After reading Dee's review and tests, I'm rather high on this OCZ.
http://www.myce.com/review/ocz-vertex-2-100gb-ssd-review-30021/Introduction-1/

It uses a lot of interesting technology. What do you guys think?
