Default H100i push/pull fan configuration - 02-19-2013, 09:28 | posts: 393 | Location: Croatia

Hello folks !

I ordered a H100i cooler to help me achieve higher OC on my i5 3570K which is currently running at 4.2 Ghz on stock intel cooler.

So i have my two Gentle Typhoons 2500 rpm fans laying around and I was thinking of using them in addition to H100is original fans for push pull config.

I thought the best would be to put the fans so one Gentle Typhoon would be pulling air from the other Typhoon and same with the stock fans so both GT-s would be on the front end of the radiator and stock fans on the other end.

Some other person told me that it would be better to put both stock fans on top for push and two GT-s on bottom for pull...

So what do you guys think ? And is the push pull with this cooler even worth it?

I would suspect you're going to create a serious imbalance in the airflow across the rad if you use 2 different types of fans. Those GT's will create far more static pressure than the stock fans, it will probably work best just swapping the stock fans for the GT's.

However, give the different configs a try and see what happens. If it was me I would just get another 2 GT's.

I have a H100 with 4 Noctua NF-F12's and seriously recommend push-pull on this cooler. I have my PC whisper quiet and the cooling is still excellent. The GT's are going to be louder than my fans but are still very good on rads.

I had a H70 before and push/pull has proven to be very good combo,
I heard that only stock fans can be controlled by Corsair link, is that corrected by firmware update somehow or the problem is still actual ?

I'm not sure my friend. I have the H100 and use a fan controller. I suspect the software/ hardware only knows a fan is attached the issues probably arise from using fans outside of the wattage the device is designed to handle but I don't know, just guessing.

This was the case when I bought my H100i a couple months ago. A Corsair rep said they were working on compatibility with other fans for a future update, but I don't believe there has been a new version of Link since then. Check the Corsair forums to be sure.

I ordered 4 of these for my h100i, not noticing that i ordered the wrong series of fan.

http://www.newegg.com/Product/Produc...82E16835181022

but it is very very quiet and does cool very well. I did however yesterday as a matter of fact ordered 2 SP fans to put on the bottom.. On top its ok to have a high airflow over static pressure..

But i recommend these.

http://www.newegg.com/Product/Produc...tem=35-181-027

BTW the reason why im not using stock fans is because i gave them to a buddy that got a h100i too and i wanted to have all the same fan (-_-) guess i failed...

From my experience with the H100i, there is very little difference (~3 degrees Celsius) between the standard fan setup and a push/pull configuration.

This is correct i have 4 stock corsair fans attached to my pump unit and not seeing much difference in temp

I have the H100i and the most recent firmware (1.0.5) running with Link2 version 2.3.4816.

Currently, I am running the stock fans on the low side, and a pair of Antec Tri-Cool 120mm fans on the top side in push/pull. Using the Hydro USB dongle, and the four fans connected via the fan controller on the pump, I can control RPMs and fan profiles on all the fans, individually or as a group.

I just upgraded my H90 to push pull with 2x Noctua A14 FLX 1200rpm and from what i saw the best choice would be push push intake from outside.
^
So 2 fans on top and then radiator.


Although I cant try that atm, need to buy new screws



Speaking of screws, Corsair is a jackass, i mean they have custom sized screws 3.5mm while in HW stores (Obi, bauhaus) they sell only 3mm or 4mm.
You can get 3.5mm but its for wood lol,

I had to buy this in the end and flatten that sharp end (3.5x30)..
And you know what it works just fine

Anyone else find the stock H100i fans noisy? They also don't seem to operate at slow speeds very well, going below ~550rpm using link software makes mine stop and start. Above 800rpm they become noisier than my 780 at idle. I used to run 3 xigmatek fans with a 360 rad for years 1000rpm very quiet.

Considering swapping them for Be Quiet! ones. Would use Noctuas, but the colour is just awful.

Yeah, I noticed that! WTH, right? I scoured my collection of screws for some matches, but none could be found.

On that note, you can barely tighten the long screws past the point the point of slight resistance or they'll strip! This happened to me (twice) while installing the radiator through my top 2 fans to the top of my HAF 932.

Mine were fine until literally last week. The bottom rear fan looking from the front of my case now has a slight, high-pitched squeal which seems to be originating from the bearing. Installed it at the end of May, so it has only been running for 2 months. I typically keep my fans on the Balanced profile in the LINK software.

I'm considering a swap as well to some quieter fans that have close to the same static pressure. This time, all 4 will be identical, but I'm not thrilled to reinstall the fans due to the sensitive nature of the holes in the radiator, as I alluded to in my last post.

Yeah I noticed the screw tightening, has happened with previous rads though seems common.

If running different brands, I would put the stocks on one side in a P/P and the GT's on the other side in a P/P. Will keep the air balanced between both sets.
