Extra fan for Hyper 212 EVO

I want to get an extra fan to supplement the existing stock fan but I don't know if I actually need one. Still, I'm looking for a fan that has a noise level of 25dba or less at its lowest setting and 82.9 CFM or higher at its highest setting. My overall usage will be applications on a overclocked and (possibly) unlocked system in an Antec 300 Illusion case with stock fans.

Here are a couple fans I'm looking at.

Are any of them good and do I use them as push or pull?

but after shipping kind of kills it.

i dunno should I buy it?


How much is shipping? it's $20 to get it to Canada :lol:  .

I just yesterday put together a new syste.
HAF 912 with an extra 4 pack of Coolermaster 120mm fans. and extra filter for door.
MSI 870U-G55
X4 960T black unlocked to 6 core @3.6ghz 1.42v
212 evo
PNY GTX 460
8gig Hyper x 1600 cas9
Corsair GS600.

With motherboard cpu temp set to 50c the EVO fan runs 1200 rpm and is quiet while running prime 95 for 8 hour stress test yesterday while the 460 was folding,99% GPU usage @70c.
You may not need the extra fan.

You will get a 2-3 C temperature improvement at most.

I'm fine with that. such difference can be a relatively decent improvement.

also are you referring to the cooler master fan or air fans in general?

I've decided to buy the CM excalibur. It is PWM and has higher max CFM @ lower dBA than the stock EVO fan, yet roughly same RPM ratio as the stock EVO fan but just about a couple of bucks more than I would have to pay for the stock EVO fan at CM's website.

Now, I have a 120mm Tricool exhaust case fan that is around 60-92mm away from the EVO and i also have a 140mm exhaust fan on top of the case above the CPU. I could:

1. simply replace the stock fan with the excalibur fan as push and allow the air to flow out of the case through the exhaust fan.

Or

2. I could pair the excalibur with the EVO stock fan if there would be a temp improvement.

What do you fellas think?

I would use the excalibural as push an the evo as pull.

would you tape over the grills on the sides of the fan case to cove the holes prior to using it as "push?"

I would leave it at first and see what the temperature is before doing any mods.

It looks like the slipstream is designed for max airflow not static pressure and it is only 1500 rpm so I imagine the static pressure is low. The static pressure on the Silverstone is OK (3.25), on the Noctura it is only 2.61. I think of those 3 only the Silverstone would be best for use on a heat-sink like the hyper series with densely packed fins.

But you can look no further than Tom's 2012 fan roundup. There is a section devoted to CPU cooling performance:

Thanks for the link, I only looked at CFM and static pressure when buying fans. I'm definitely getting a couple of Silverstone AP121's soon. http://www.newegg.com/Product/Product.aspx?Item=N82E168... .

Edit: sorry for the double post, been having intermittent problems with this site for the past few days.

in light of these posts I'm now leaning towards the blademasters. More bang for the buck and better value overall imo, it is PWM and has the highest static air pressure for hyper evo cooling at an affordable price even though it's worse in other areas but only by a little.
March 15, 2012 5:35:04 PM

Update from Cooler Master Tech Support: They said the 120mm blademaster's static pressure is 4.27mm/H2O! I'm thinking may be he accidentally incorrectly read it from the 92mm(?) I asked them to re-check the estimates and that's what they said. Initially they told me that the Blademaster and stock EVO fan had pretty much the same air pressure but after I asked them to give me an exact estimate that's what they said: 4.27mm/H2O (Blademaster) and 2.7mm/H2O (EVO) respectively.

+1, not even 3C. the HS is too thin for dual fans to make a difference.

March 23, 2012 1:57:21 AM

Doesn't the EVO HS have densely packed fins? Then what bang-for-the-buck HS is reasonably thick enough for dual fans to make a difference?

I have just the single fan on the EVO. no need for another.
March 25, 2012 3:34:44 PM

I want to get an idea of how much more I would have to spend to buy a HS (minus the stock fans) thick enough to take advantage of a dual fan push/pull configuration to produce a significant temperature drop, i.e., 5-6c or more(?).

The EVO costed me $21. I'm willing to spend around $20-$30 more ($40-$50 total) for a more efficient HS minus the stock fans it comes with, since I'd be cooling it with a pair of Blademasters.
March 25, 2012 3:45:56 PM

ALso, i heard that if using two different fans on a pwm splitter cable that has pin 3 on both female connectors, that it will cause issues and conflicting rpm readings from the mobo. so pin 3 would need to be removed.

but do i need to remove pin 3 if both fans are the same?

check out the Hyper 612 PWM then ($50), it's almost twice the depth of the 212+

You'll never get 5/6C temp diff push/pull = don't care what fans you use!
Been there done that,usually 1-2C temp decrease 3C if you're lucky.
Push/pull and some very good paste and you'll see a 5C decrease probably,6 max if you're lucky.
March 26, 2012 10:46:48 AM

ok thx for the suggestions but that looks too big and the xtra double cost dont seeem to match the temp diff.. ill keep the evo & 2 bms. and settle for 1-3 C improvement...

why the sudden interest in push pull? are you trying to lower temps or lower noise?

P.S. i would just stick with the evo in single fan operation.

some very good paste

like what?

I have a 7 year old AS5 compound lying around.

Are any below go really well with EVO HSF and 960T?

Shin Etsu G751
OCZ Freeze
TIM Consultants T-C Grease 0098
IC Seven Carat Diamond
MX2
AS5

how many degrees cooler are they than the AS5 that is worth spending extra money?

i have $4.40 ebay bucks and $7.15 Amazon GC.

both

i already got the 2 bms so migght as well use it in push pull to get that extra 2-3C. and if i put some good paste i might add another 2-3C ;)

even with all that you will be lucky to get 3c improvement. not worth the time if everything is working properly with your evo. if you don't like the noise, get a slower RPM fan.

going from CM compound to AS5 is only a 2c improvement (so is going from mayonnaise to AS5)

well I have some very old AS5 lying around. a 2C improvement is not bad imho.

isn't even 1C change in weather noticeable to the human body?

your PC is not a human body and unless you can win cash for OC your CPU the highest it can go or have some CPU OC contest where the loser has to drink pickles & milk, cooling 1C to your CPU is lot like drinking diet soda with your 1k calorie burger & fries.
