** NEW CORSAIR LCS OFFERINGS AT OCUK **

It's the fans. Corasir have just raised the PWM rate to remove the rattling noise which has introduced a higher pitched noise instead. If you hold fans still you can still feel them vibrating.

In the forces we would have called this fix a bodge. Corsair need to realise the stock fans are junk and send out a set of proper SP120 fans to those affected as these work fine.

I'm sure they will come up with some other bios that will just break something else, my faith in Corsair to deliver a product has all but gone if this is the level of testing they do and how they fix.

And people trust their psu's....?

Thanks for the heads up about the SP120 ones, I was waiting for someone to mention them. I will definitely invest in some of these as they seem to get really great reviews.

Just connected my Arctic fans and although the H100i seems unable too control 4 pin PWM fans very well there is no buzzing and the cooling is just as good as the stock H100i fans in a pair.

Edit - Just noticed that with the Corsair software running my GPU idle temp is nearly 55.c ? If I close the Corsair software it drops back down to 38.c....

I'm just going to use my mainboard to control the fans using my 4 arctic PWM fans on a splitter. I really do not trust this Corsair controller or software at all.

Here is a video showing the noise the stock H100i fans on the new (Fixed) bios now make..

Finally fitted mine tonight.

• There was a rattle at low rpm on power up.

I had already downloaded the latest firmware and corsair link earlier today and did a flash without any issues as people have reported, I do have that faint "whine/buzz" though.
 
I have now installed the H100i with my 4 x Arctic PWM fans in push pull. This gives nearly a 5.c difference over the 2 x SP120 (Not the stock ones) fans and it remains nice and quite.

4 x SP120's might give better results but they are not as quite as the Arctics and also over twice the price.

My i5 at 4.5ghz now under load has a max temp of 65.c....

Corsair doesn't build it's PSU's....


But there's now no way I would touch one of their CPU coolers.

But built to Corsair specifications, not their own. Builder can only build as good as the specs the buyer give them. Only option builder has is not build for that buyer. Many quality products have fallen to this same problem when big name companies require them to cut production costs/change their specs to meet chain's requirements. :(

I had 2 H100i's turn up today and both suffer from the low RPM fan rattle problem. This is once again very poor service from Corsair considering the issues with the original H100. They have said on there forums there will be a bios fix to the H100i and they have replicated the problem in the lab.

Shame they seemed to completely miss this in quality testing.

I guess the maxim with this sort of thing is that these sort of things are still the preserve of those too lazy or inexperienced to install a proper water cooling setup.

That's not a criticism of anyone, I find myself in that boat too, it's just a shame that these products seem to still have quality control issues that really ought not to exist for something costing ~£100.

:(
 
Really cannot be bothered with all the hassle of water cooling for minimal gains over the temps now. When they work these coolers work well its just getting a good one...
 
Received my new H80i today & finished installing it a couple of hours ago. Took slightly longer than expected due to a couple of issues, though however I've ran into no problems with the installation and it seems to be running nicely ...just about lol.

Couple of grumbles, the manual states that the kit is supposed to come with 8 washers for the fan bolts. Mine however only came with 4, I've also read on another forum the other day while researching into this cooler that other people have also only had 4 of these washers supplied. Second is the amount of spelling mistakes in the manual itself :rolleyes: Lastly, when I fitted the backplate onto the motherboard, I noticed that their was still a lot of play with the bracket after screwing in the double ended bolts. Though the excessive play with bracket was resolved when the cooler's pump was screwed into place onto the CPU.

Powered on the system and after a slight issue with the computer not detecting the Corsair USB connector on one of the USB headers & after swapping to another USB header everything seems to be running smoothly, got a nice 26c idle (was 30c on my Noctua) & 48c load. I also managed to set up the Corsair link software to how I want the cooler to run.

One thing I have picked up on & something I was expecting, mine also had the buzzing sound from the fans at low RPM. After updating to the newest firmware, this did indeed cure it but as also expected - the slight whine noise is now present!

Despite these minor niggles, so far I am very impressed with the cooler. I have noticed a decrease in CPU temps & despite the abnormal sounds from the fans, they do run very quiet at low RPM's (more than expected after hearing the negatives regarding the stock H80i/H100i fans) and lastly the cooler looks the business :)

It does look cool, that's why I want it:) I can't decide on H80i or H100i? I can fit either of them. My case is CM Storm Scout 2 and have room for H100i on top, but don't know If I want that?

It will look even better when I receive my windowed side panel for my R3 case this week :D

I was in the same situation as you too as I was seriously considering the H100i but in my opinion I'm not going to the extreme with overclocking & cooling and after reading that the H100i is a bit of a tight fit in the R3 case I opted to go for the H80i instead and I'm glad I did as I realised tonight when fitting it that the space between the top of the motherboard & the case is very minimal, by this I mean moving the exhaust case fan from the rear to the top of the case, which proved this - as now I'm left with literally a 3mm gap between the case fan blades & it's cable, and the H80i fan cables too :eek:

Not only that though, but I've also come to the conclusion that the combination of having a Fractal Design R3 case, the MSI Z77 Mpower motherboard and the H100i would not work (well I'm 99% certain). Even though my R3 is H100i compatible, the thickness of a H100i radiator & fans attached to it would hang too far down and would not simply fit because of my motherboard's chunky heatsinks above the CPU also which would totally obstruct the cooler fitting into place.

I also got a bit put off as well by the amount of reported problems with H100i other the past few days, the H80i has had reported problems too but when it comes to something like this, I could not simply justify myself spending nearly £100 a CPU cooler that could potentially go wrong for me down the line. The H100i is reported to perform slightly better than the H80i in terms of performance temperatures but not by very much, only something like by 2-3c.

I have been doing a bit more playing around with this and comparing it with my H100.

The stock fans are crap and nowhere near as good as a proper set of SP120's but neither the stock fans or SP120's give amazing results and seem to give equal results on either cooler give or take 1-2.c. The stock fans are considerably louder than the SP120 fans.

I have now set up the H100i with 4 x Arctic PWM fans and have connected these to a PWM splitter that uses a molex for power and the mainbaord for control. Set up in a push pull config with a Normal profile setting in the bios.

Using these fans on the H100 in the same setup my max temp whilst running prime was 72.c on the H100i this has dropped to a pretty astonishing 58.c. That's 14.c lower temps on the H100i.

It seems the H100i can give better results if you increase the airflow through the Rad over the H100. With the 4 x Arctic fans I get the same results as the two stock or SP120 fans running at max RPM. This is with the fans on auto.

I imagine using 4 x SP120 fans will give better results as they push more air but finally I'm happy with the H100i and my setup is just about silent even under load.

Amen....

Fractal Arc mid, H100i 4 x Arctic PWM fans.........

I've decided to get the H80i because I'm not going to OC that high anyways. So the H80i will do the job. I just need help finding a LED fan that will work with the H80i?
