Disappointing H100i perofrmance - your input needed.

Three pages and no one has asked the obvious ! I'm disappointed !

Firstly how is your pump power connected? have you connected it to the motherboard?

If you have then it's highly likely that your motherboard thinks it's a PWM fan and if so it could be running your pump as low as 3v.

I had a similar issue with my Coolchit Epoo II (Corsair H60) my pump was running at around 50%.

If you have it connected to the motherboard go into your bios and turn the fan (well, power) up to 100%.
 
I would buy MX4 and when it arives take the H100i off and clean the cpu and the cooling plate with kitchen paper. Make sure no thermal paste is left. Then put a rice grain sized piece of mx4 in the middle of the cpu and push the cooling plate on the cpu. let the cooler spread the paste by twisting it a little while pushing in on. make sure you have proper contact everywhere and then mount it back on.
 
Do you use the Link software ? try to update the firmware on the H100i and make sure you have got the pump set to 100%.

The pump gets its 12v from sata... The speed of the pump is fixed.. The fan header is only for pump speed indication... I think
 
The pump runs at 12v from sata and there is no way to the pump can change speed. I have no idea what the 4 pin cable that comes out of the pump is for.... There is only one cable threaded into it...


Well i didnt know that.. i didnt even install the link software on my pc and my h100i is still running fine :D The cable is for a 4 pin fan header and it iw the PWM signal to monitor the pump speed

Then tbh it sounds like the pump is faulty. With my cooler I connect to the motherboard then ramp the speed up to 100% (or 12v) through bios.

The temps he has are completely wild and not due to the TIM IMO. If the TIM was that bad on the H100 they would all be returned..

A mate of mine had a H100 with a faulty pump and had the exact same temp issues being shown here.

If they were 10c out? yeah, maybe some top notch TIM could save the day but his idle temps are higher than my load temps, overclocked with a rad half the size.
 
Hey guys thanks for your response.

1) What's a TIM ?

2) How do I know that the pump is functioning ? In corsair link i see it running at 2300 RPM or so...

3) I have an ASUS Z77 Deluxe board and I have disabled the q-fan things. I'm controlling the fans via link and AI Suite.

4) How can I verify that the CPU has full contact with the pump ?

Thanks again for your help.
 
you can if you like but i hope you cleaned everything up first or that would be counter productive. i have mine at 4.4Ghz hitting max temps at full load under 60'C idling around 30

hello,

My CPU is a 3770k running at 4.4ghz @ 1.240v.
Well, I've watch a bunch of H100i installation video, and The pump is really tight and it must be pressing the CPU firmly.

Should I just buy a MX4 paste and try to apply it ?

TIM = thermal interface material, or thermal paste.

If it's running at 2300 RPM then it should be working.

Are you absolutely sure that you have mounted it properly? It mounts the same as mine and I can tell you *I* have mounted mine wrong before. Basically I over tightened one corner and it wasn't sitting completely flat so my first core was hitting crazy temps.

Can you download Realtemp here

http://www.techpowerup.com/realtemp/

Then put a load on your CPU and show us (or tell us) your temps? I want to know if this overheating is uniform or specific to one/two/whatever cores.

What's your vcore ?

The voltage for your CPU.

  1. TIM means Thermal Interface Material, more commonly called thermal paste or thermal grease. It's the grey-silver looking stuff, usually in a syringe, that comes with your heatsink/water block. The Corsair H-series coolers (and pretty much all AIO -all in one- liquid cooling solutions) usually come with it pre-applied.

  2. Dismount the pump/block from the CPU, disconnect all other connections to the PSU except for the pump, and then jumper your PSU (WARNING: It's best to do this with another PSU other than the one in your rig, just in the off chance that something happens to the PSU) by taking a paper clip and unbending it and pushing one end of the clip into the hole where the green wire is on your 24-pin cable, and the other end to any black (ground) wire, and turn the PSU on. You should be able to hear the pump running.

  3. DO NOT TRUST AI SUITE!!!!!11!!
    I, and a few people here, have said that AI Suite is inaccurate as all heck when it comes to fan speeds and temperatures. Use something like Core Temp, SpeedFan, etc. to control your fans if you must do it that way. I personally would say either hook them all up to 12v via molex (unless they are very loud), or buy a 5.25 bay fan controller.

  4. After dismounting the pump/block from the CPU as in #2, check to see that there is an even layer of thermal paste on the CPU heat spreader, and on the copper cold plate of the water block. When re-fitting the block, tighten the screws in an X pattern, making sure to tighen all 4 as evenly as possible.

Seriously people? Asking him to change thermal compound? The compound on the H series is some of the best, I would stack it against Arctic Silver and MX as well as Noctua any day. My H100i 4.6ghz 1.356v 2500k and my temps NEVER exceed 75c on a 24 hour run. I am also using stock thermal paste and SP120 silent.

Oh and look where I live.
 
we are just trouble shooting, and ive been tempted to push up to 4.6 but unsure

rememeber300 - what vcore are you running ypur CPU at, and do you have HT on ?

I'm not going to jumper my PSU, thanks.

KING_OF_SAND - When you conduct the test run, what is the ambient temp ?

sounds like you havent mounted it properly. either that or you have left voltage on auto. = a big no no.
put everything back to stock.
make sure everything is powered properly - pump & fans. tighten screws on cooler.
 
Hello

1. Anyhow, Installed the h100u today (a new device). idle temps are at their 40c and that's with the Corsair AF120 high performance static pressure. Load speeds reach 85c (overclocked OC running at 4.6ghz @ 1.285v)
What am I doing wrong ? this isn't brain science, why must everything not work properly for me.
I installed the fans to exhaust air from the top of the case so it's pulling air from the case outside.

2. the SP120 High performance edition.
high performance static pressure fans max speed is 2000 RPM instead of the asserted 2300- why is that ?

Thanks,

Mike.

hello mike,
have you re-installed the OE fans that came with the H100i? retest, before
gutting the system... you know the SP120 are a lesser fan... in pressure and
air-flow. and it is expected to make the system run a bit warmer in a loaded
situation.

your question on the fan speed would more than likely be from the fan header
is not supplying 12v to the fan to get correct speed or reporting error.
 
Update: Well, today I decided to delid the CPU and reapply the X4 tim
idle temps are around 35c and stress are 65-75c.
Downside - For some reason, it wouldnt see sticks of RAM installed on the blue DIMs (asus z777 deluxe)

you might wanna get a magnifying glass out and see if you nicked the PCB.
this has been reported that after de-lid, they'd managed to knick the PCB
and shut down the PCI lanes to the RAM/MOBO. also, see if the plates on the
under-side are not damaged or the pins in the socket are tweaked.
