mITX CPU cooler

[BesiX]

I recently discovered my H100i wasn't cooling my 3770K properly in my Bitfenix Prodigy case. (OCCT standard test was aborted after 9 seconds @ 92 °C...)

I wanted to replace it with one of my spare CPU coolers, but I noticed my TPC 800 and 412S are just too big and would need a 90° placement. This way the air flow won't be optimal.

So now I'm looking at some (air) CPU coolers that won't block the RAM slots or PCI-E slot. (I've got a lot of low profile RAM here, so that won't be such a problem though.) I've found the Scythe Shuriken rev.B, but I'm concerned about the cooling capacities...

The system that it will be used in:

CPU: i7 3770K
Mobo: GA-Z77N-WIFI
RAM: 2x 4GB Corsair Vengeance DDR3 PC12800 (got low-profile RAM as spare if low-profile would be needed)
GPU: EVGA GTX670 FTW
PSU: Corsair CX600M
SSD: Samsung 840 Pro 256GB
Case: Bitfenix Prodigy Black
Case fans: Thermaltake 230mm blue LED in the front + Scythe Gentle Typhoon as exhaust in the back

Id actually work out why first mate...... The H100i can cool that CPU no problem and I know you cant overclock with your board so you should have an issue.

Look at ouroverclocking guide and follow the undervolting steps also

Did you have this processor for a while before it started displaying those higher temps? Also have you attempted to reseat the H100i's heat sink? Could be that it's not on properly. Having worked with this board a little bit I am fairly certain that you can't control CPU voltages, or if you can it's only a voltage offset that you can control, however you CAN change the multiplier. Check to make sure the multiplier is set appropriately. If you HAVE changed the multiplier, perhaps you are attempting to push the chip a bit too much? There is also the chance that the pump has taken a poo in your H100i, you can also check to see if it will turn on with a jumped PSU with the rest of the computer turned off I think.

Well, I've checked the pump in the BIOS and it showed the right RPM value (2200 RPM), so the only problem I could think of was unproper installment.
I reseated it, but the problem still happened.
Every component in the system is new (only used it for less than 3 hours as it's not my main rig).. I also then tested each component on my test bench and no faults there...

Just because installing the H100i in the Prodigy case is such a b*tch, I decided to go for air cooling instead. (In my other Prodigy case I've got a H60 and it performs well, so that could also be an option, but I just prefer air cooling at the moment.)

Since I'm not overclocking the system for now, I installed the stock Intel cooler as a temporary substitute.
I'll test the H100i again in a few other rigs in the next few days to see if I can pin-point the problem.

I have a friend with the same board as you...
You can't adjust any voltages with it so I'd think that was your issue...

 

[BesiX]

Adjusting voltages isn't the problem...
The H100i just wasn't cooling the CPU (at stock values).

The H100i just wasn't cooling the CPU (at stock values).

There's an issue with either your mounting, or the H100i, or the board.
The h100i should have absolutely no problems in cooling even a pretty heavily overclocked 3770k.

Can you run OCCT with CPU-z open too, and tell us what the core voltage goes up to while under load?

 

[BesiX]

Well, I think I've found (part of) the problem...
The Y-piece you can connect 2 fans to had a loose connector. The connector you plug into the CPU cover had 8 loose wires. Without any effort you could just take those out of it.

What I'm talking about:

Since I was only using a push configuration, this ofcourse means my fans weren't spinning.

 

[demonking]

so did this solve it?
i got an h70 and put the 2 stock fans from the prodigy on it and it cools just fine (52c after 3 hrs of BF3) and was thinking about putting an h100 in there instead.
do you have yours in the front or top?

I put an air cooler on the CPU, the H100i is working alright in another PC of mine now.
