H100i Faulty?

thedozyone · 31 Aug 2016 at 14:18

I have a H100i which was a refurb and I've been having a few heat issues.

Last night I took it out and put some fresh thermal paste on (cleaned off with TIM) and Prime was showing 90 deg +!

Corsair link suggests the pump is running but I can't hear it also I don't feel any heat in the pipes.

I've had over 2 years out of it and I think refurbs only covered for a year but what to go for next??

I was looking at the H110i GT or the H115i. Or any other alternatives?

I'm not sure I'm up for a full watercooling loop yet. This is about as close as I can put water near my PC!

How about an expandable AIO? Then you sort of have the best of both worlds.

Alphacool Eisbaer
Bequiet Silent Loop (not out yet, made by Alphacool)
EK Predator
Fractal Design Kelvin (made by Alphacool)
Swiftech (forgot the name)

Thanks for that

The Fractal one looks interesting although people complain about noisy pumps.

The EK might be a bit too watercooling for me!

The H100i has been pretty good up until now and is very quiet (probably a bit too quiet now

)

The Eisbaer is pretty much the same as the Factal one but with a newer pump, so it's very worth looking into.

(The Fractal has the same pump as Eisberg which is the old version of Eisbaer.)

Also if you find it noisy you can lower the voltage with little to no performance drop.

Cheers for the info

What about the Raijintek Triton 280mm?

The Raijintek is not really expandable because it's an aluminium rad, and there's plenty of complaints about the quality (cracking leading to leaking), see this thread...

Is your CPU overclocked? What version of Prime are you testing with? It's quite common for Haswell CPUs to jump to crazy temps when using a version of Prime that supports AVX2. My 5820K at 4.5GHz will jump up to 90+ within seconds if I use an AVX2 version of Prime.

I believe any version of Prime before 28.5 doesn't support AVX, so either try an older version or use something else to stress test.

I just downloaded an older version and it still went to 88 but hasn't gone above that so far. It's O/C'd to 4.4

Looks like it's my overclock!

I just ran it at defaults

Did you manually set your voltage for the CPU overclock?

I know for my 5820K if the voltage is set to Auto it applies a very high 1.25V; when 1.08 is more than sufficient for a day long AIDA64 stress test.
It's worth noting though, that even with just that 0.08 increase from 1.0V my CPU temps went up 10 degrees at Max peaks.

Might be worth checking the voltage to see if you can knock it down a bit.

Also remember that the 4770K did not have soldered TIM under it's IHS. This results in higher temps as well.

Here's what my system under Aida64 runs at stock vs overclocked.

Without Overclock

With Overclock

I'm just using the auto which is probably why its getting so hot anyway.

I need to mess around with settings but haven't really done that for a while.

For 4.4 on a 4770k what are the best settings to start with? I have an Asus Maximus Hero VII

I don't have any experience with that CPU, but get something like Core Temp and AIDA 64 Extreme ( trial ) which shows the voltage used under load.

Then note than, and slowly knock it down as you run the stress tests to see what is stable for the OC. Each time you lower the voltage the temperature should lower as well a bit.

If you're running on Auto chances are more than 1.35V is going through the CPU. Download CPUZ and run the test again watching for voltage changes.

Auto overclock settings suck. I would try 4.4-4.5GHz with 1.25v and go from there.

Cheers for the comments. I'll have a little play later
