Possible defective H100i ?

Postposted on Fri Jun 27, 2014 8:33 pm

So I've had my new system for a few weeks now, Asus Sabertooth MK1, i5-4690, 780ti...

The i5 was a place holder until my 4790k arrived, and it did today.

I carefully swapped the CPU's, fired up the computer into Win 8.1, no over clock, sanity reboot, then fired up Prime 95 to make sure all is well.

Using HW Monitor, CPU was at 26 idle, as soon as I clicked on START on P95, temp changed to 99, then started to creep up to 105.. shut her down, rechecked CPU was seated and cooler was snug.
Re-did test, same thing.

Now Corsair's software is crap, will not show pump and fans in Win 8.1, so I swapped in a spare SSD, installed Win7, drivers, etc, and Corsair Link.

Re-did my test, same thing, and software showed temp of H100i at 26-28 when CPU was hitting nearly 100c. Since I had my i5 right there, I swapped CPU's, did same test..

Pretty much same result, CPU went from 26 to 90 in a second.

I'm thinking the pump is not working on the cooler or motherboard is bad, but I am fairly sure temp sensor is on CPU itself.
CPU is well seated, thin even film of paste when I removed cooler to check.

I never ran torture test before today, but my temps never went above 45 or so, which I figured was normal for huge cooler and a stock i5.

I've opened a ticket with Corsair, and I may go pick up a decent air-cooler to run more tests tomorrow.

Any other ideas?

I can't add anything of value, but I was looking towards getting one of those. Gonna watch this thread closely.

I assume you checked the thermal grease imprint to make sure you're getting good contact?

Can you hear the pump running in the H100i, and does the fan spin?

Broken pump, for sure. They're audible when they're running - you should be able to hear and feel the pump on a Corsair AIO.

Despite the high profile on review sites and adverts everywhere, Corsair's coolers are fairly mediocre; They're not the cheapest, they're a long way from being the quietest, they're not even the best performers and there are enough forum posts to indicate that the pumps aren't the most reliable, either (though the ones I've built with are still going strong).

What Corsair *does* have is a really solid warranty procedure with great customer service. Once you get a working one back from RMA you'll probably be perfectly happy with it for overclocking.

I feel a slight vibration when I touch the pump housing, but not change in sound/feel when I crank up the pump speed.

If the magnetic impeller is jammed or running waaaay too slowly you'll still feel a vibration.

If the baseplate is making good contact with the cpu, but your temperatures are shooting up fast, it can only mean that there is no water flow. Even if the pump is spinning, something is blocking the flow and you'll void your warranty opening up to see what the problem is.

Pump for sure. You might as well not have a cooler on if the pump is not working.

Running on the stock Intel cooler now, hopefully Corsair gets back to me soon to start RMA process.

Question, are the Cooler Master watercoolers any better quality?

Cooler Master's heatpipe coolers are excellent. Haven't used their water coolers though.

I would first try a different cooler to double check on mobo sensor.

If you're returning your H100i rather than replacing under warranty, the CM Seidon are the 120/240mm equivalent of the low end (old H60 etc) Corsairs but, according to most places I read, both cooler and quieter at any given level. Silverstone's Tundra are highly rated but also very expensive, the main thing being that they're quieter. If you can cram 140/280mm radiators into your case you should consider NZXT's Krakens which frequently get top marks for noise and performance. I've never seen a CM Nepton (their 140/280 line) in the flesh but Frostytech seems to have an incredibly high rating for them, and Frostytech's results for other things are mirrored by my own experience.

Corsair's coolers aren't bad, they're just CoolIT system rebadges. CoolIT mostly design for big OEMs though, and the key factors for an OEM are to meet a specific quality for the absolute lowest cost, not to design the best quality/performance for a specific target cost.

If you want to make the decision based on your own reading I tend to go to Frostytech for most air cooler reviews but you'll find plenty of "Corsair vs Other" tests from places like Bit-tech, Xbitlabs, Anand, and perhaps Martin's Liquid Lab, now that he's testing kits as well as custom loop components. Whilst they don't have any current Coolermaster reviews, the chart on this page covers a lot of everything else

Corsair 750D, so lots of room, not sure if I need a 280mm though, mild overclock on a 4790K.. the 140 may be more than enough cooling

If your having trouble hearing the pump running on the Corsair unit Luckily when you try the Air cooler you can plug the pump into any active power source and hold it up to your ear. When Installed on a system using a long skinny screwdriver place the tip on the pump head and put the handle against your ear flap opening closing it. This makes a stethoscope that amplifies the sound from the pump many times even though the sound is traveling up the screwdriver through the handle onto your ear. EDIT: make sure the driver has a plastic handle....rubber handled driver will work but the rubber dampens the sound you can hear. To get a idea how many times the sound is amplified take your index finger and gently hold the hole on your ear closed. Then lightly tap or scratch on your fingernail. you will hear it at least 5 times better then if you do the same thing directly next to the opening of your ear.

I have used this technique literally thousands of times " mostly on cars" but many times on computers to find a noisy component that is hard to find.

If the pump is working it might be empty from the factory. Possibly the cooling filling machine went dry before they noticed and a few units went through the filling station and somehow your made it through QQ.

I would just keep the H100i once you get the replacement. I have not heard a lot about QQ problems with their units. Since you do have a devils canyon CPU and they transfer heat a good bit better then the previous Haswell chips I would hang onto the 240mm setup since you have plenty of space in your nice case. From what I have been seeing with Devils Canyon is they can take a lot of volts andthat equals heat. You can never have a cooler too good, but you can have one that is @#$% like the intel box cooler.

Any specific reason you want an H100i? Aside from the weight, I think the Notcua NH-D14 or D15 are as good or better on the cooling front, and tend to be quieter. Its just a lot of weight on the CPU socket area, and therefore not recommended to be attached when moving the computer.

So anyways, if the H100i keeps giving you problems, you can check out the Noctua dual fan coolers.

I like the AIO coolers since they do not stress the MB socket like a heavy air cooler does. Also they make the CPU socket area nice and tidy without worry of using memory sticks with tall heatspreaders.

Also the Air coolers throw off tremendous amount of heat inside the case...so if ou plan to use one make sure your case has good airflow in and especially out.

The good AIO coolers provide the same if not more the amount of cooling as the top air coolers but for some reason do not push out nearly as much heat as the air coolers do. I do not know why this is the case but AIO's just do not throw out the concentrated heat Air coolers do...it is strange.

Gluck with your choice and i hope your up and running quickly.

I haven't decided yet, I'll see what Corsair says, if they ever answer me.

If I have to purchase another cooler, it won't be a Corsair for sure.. The reviews at Frostytech seem to favor the CM 280, overkill for sure, but I do like the rad at the top of the case, makes for very natural air-flow.

Well, for most air coolers, you direct the air right out an exhaust port, maybe even one with its own exhaust fan. I actually have my EVO 212 pointed up so it vents out the top of my Carbide 500R, similarly to how an H100i would vent.

No doubt that AIO's keep the CPU socket nice and tidy tho - but I'm not a fan of tall (and of dubious utility) heat spreaders on my ram, so no big loss there.

Don't all of the heavy aircoolers use backing plates to reduce stress on the motherboard socket/brackets? This does, of course, make retrofitting a new cooler to an existing system a PITA though, since you need to pull the motherboard unless your case has a CPU socket cutout.

I don't think I have *ever* bought RAM with heatspreaders (though I have acquired a few as hand-me-downs or in trade). Kingston ValueRAM forever! :lol:

They do, but you still don't want to be moving a system with a Notcua style cooler around to much because it is a lot of strain on the board.

I wouldn't worry too much about that, given all the pictures from the Pentium 4 era showing motherboards visibly bent by the stock cooler retention mechanism; I think the motherboard can take it. (Although I suppose things may be a little different now that everything is ROHS-compliant... good ol' leaded solder is more durable than the newfangled lead-free stuff...)

ok, I never got a response from Corsair, and in the meantime I picked up a CM 280L.

So far very nice, any tips for what to set the fans at?

Right now have them set on Standard profile, they run at 700 rpm, and go up if there's load on CPU..

Better way to set them up?

Also, on my 750D case, 3 140mm fans, all pulling into case, and the rad fans at top of case, pushing out.. best setup?

Depends what overclock you're going for and how much you can tolerate fan noise. There's no right or wrong because it's down to your personal preference.

Does the 280L come with PWM fans? You get the best of both worlds then....

Comes with 2 140mm PWM fans. I let the motherboard do its auto-tuning, it set single core multiplier to 46.. fans go up and down in speed, haven't seen above 61c yet.
