Radiator fans for XSPC 750 Raystorm RS240

[bulldog1963]

I just want to start with this: I wanted an entry level kit. I looked at all the ones readily available to me. I looked at the dimensions of the radiators in each of the kits I could AFFORD (I am not wealthy like many of you - not a dig, i just cant spend more on a custom loop than i did on my whole computer - and have recently become unemployed).

Based on these factors and my case's (Cooler Master HAF XM) capabilities (45mm x 280 (max) external mount with internal fans or 33.6mm x 280 internal mount with external fans) I was gonna switch out the stock 3-pin fans http://www.xs-pc.com/products/radiators/fans/120mm-1650rpm-fan/ with Cooler Master Excaliburs http://www.coolermaster-usa.com/product.php?product_id=2965 that I already use (quite successfully on my air cooler in push/pull) in a push config because my internal space is just a hair too little to hold the 35 mm radiator.

I like the idea of using PWM's and the profile seems to work well. They are the same dB at 2k rpm, have twice the static pressure, and 20 more cfm than the stock. Now, I've seen very little on the FPI specs for the rs240 radiator's FPI. Nobody mentions it, really. I did find 2, though. 1 just says it has sub 8-fpi. The other, though, actually MEASURES and shows the pic at 13. I've read that on low FPI lower cfm's/pressure are adequate but more is better, just louder. Obviously, the higher FPI's NEED a higher pressure to work. These fans can't even be heard, really, cuz I have 3 140's at about 39 at 100% all the time.

Anyone see any issues with using these Excaliburs over the stock? I have them anyway so I figured why not put them to use.

The RS 240 would do well with Yate Loon HS fans. It's a higher (not silly high) FPI rad. The RX rads are the better lower FPI rads. More $$ too.

If budget is a concern, the Yates at Sidewinders is your best bet. They have been a radiator standard for eons. You can slow them down if you like witha cheapo controller. It's cheap, good wattage, and has been used by lots. It's a good effective one for sure.

Lastly, NEVER trust the marketing hype. Your welcome to look in our stickies and some external links for fan tests.

Yeah...limited by the thickness of the radiator. the rx ones are 55mm thick. Too thick for my case. I am not willing to cut holes, remove lids, tape **** to the side of my computer, build a rack for a radiator or anything insane. I want it compact and inexpensive as possible for the moment yet effective. I cannot afford the best, but I can afford a starter kit to get into water cooling and reap the benefits from it.

When I win the lottery, i will look for higher quality rads, blocks, and pumps that fit inside the case that I have at that time. I have room, if I want to expand later, to throw in up to 1 140, 1 280, 1 120, and 1 240 (with yate loon slims) in addition to upgrading my 240 to a 280. All without having built a monument to miniature car parts sitting in my living room.

Forget the YL slims. They have NO pressure ability. Not neat enough for a rad. Pretty worthless IMHO..

Here is testing on the XSPC RS. Perhaps we looked at the same because Martin gets 13 fins per inch (fpi) from 2008 and in 2012 got 15 fpi. That is a "medium" fpi. Notice in the second test it finished neither at the top or bottom. In the summary of the testing Martin called the RS the "all-around value" in the "bang for the buck" category.

Your PWM solution seems to be worth a try especially if it does not cost any additional money. Good luck.

Just found this review for my "improper" fans...LOL

It is a bit dated but results are results. http://www.techreaction.net/2010/02/18/cooler-master-excalibur-fan-review/. Looks like these Cooler Mater Excailburs outperform the favorites, Yate Loons, and the GT's. Hmm. Send any of your responses as to the superiority of these fans to the tester, please. I just found the test. Argue with him .

Yeah, musicfan. We probably did see that same one.

It was said that a low FPI rad is better, which to me goes against the laws of physics. I thought that with higher FPI you have greater surface area to cool better. You need a higher pressure pump to move the liquid and higher pressure fans, but ultimately the cooling is much better. Read in a different thread in a different forum about the quality of a 22f FPI radiator being a more efficient cooler than the, relatively, open-air ones i have seen pics of.

Here's a link to the cooling surface area of radiators. you can see that the radiators that have greater FPI have greater cooling surface area, thus, better at cooling. What's cool? It is on this VERY forum! http://www.overclockers.com/forums/showthread.php?t=626885. So, my conclusion, along with those in the thread is that greater FPI>lesser FPI in the ability to shed heat.

Greater FPI = more performance, more noise
Less FPI = less performance, less noise.

We recommend less FPI because usually people don't like to use 6000rpm screamers for their radiators and less FPI fans perform better than their higher FPI counterparts with standard fans.

 

[Conumdrum]

Okay buddy. Your right in all respects. Your Coolermaster fans are decent fans. More FPI is better to shed heat.

What we think is right might not be what you think is right, so it's all good. Looks like you already have it figured out, so since you have good fans and a great rad, what's the question again?

I didn't spend the time to look at your fans initally, glad you took the time to do so yourself.

It's all good.
