H100i V2 Disappointing Performance

[TechGuy10]

Hi all,

 

Purchased an H100i v2 from a user in the Aussie BSS facebook pc community and I've not seen the performance I've been looking for when I installed it.

 

I've been using the cooler in a NZXT H440 in the top mount position and had the block seated on my 4790k. I previously used the Coolermaster Hyper212 evo (which was great) but wanted to push some overclocks so I found this one. Unfortunately when I installed it, the idle temps have been around 10 degrees warmer and the load temperatures were about 10 degrees warmer again. I've tried 3d printing some washers for the backplate so that it would be more snug on my motherboard (asus mobos have varied pcb thickness causing oddities with mounting apparently), I've reinstalled the old cooler because it still works better. Though when running an AVX workload (y cruncher) they both get equally hot (around 90-100c) so I'm thinking I may have spilled some methylated spirits into the gap in the black silicon on the processor and washed away a little bit of thermal paste.

 

Any help now is appreciated, I want to delid my processor but I want to get this sorted out first.

 

Thanks

are you sure about your fresh thermal paste application? first thing i'd check i'm pretty sure getting anything under the IHS is pretty much impossible and delidding on 4790k won't do much either

were the pump + fans working normally?

So THERE is only 2 options

 

1. CPU TDP IS EXTEMELY HIGH
2. WRONG MOUNTING ON CPU
3. COOLER PUMP NOT WORKING

Solutions

1. Re Apply Cooler and read manual
2. Re Apply Thermal Compound
3. RMA the product on the Manufacturers website

I've remounted the cooler twice or three times over the last few weeks of working on it. Both with some average thermal paste that came with my hyper212 and some arctic silver 5 that I bought.

My 4790k is running stock which at around 88w shouldn't really be causing an issue.

I would like to OC but as soon as I set 1.2V and start the Aida stresstest, i'm in thermal throttling pretty hard 100C and 15% clock reduction.

My confusion is the relative better performance that my fairly average tower cooler is giving over what is supposed to be one of the better out-of-box solutions before custom loop and other exotics.

They seem fine, the pump and fans all show in corsair link and show that they're spinning at around 1600-2000 rpm. The fans are a little noisy but that shouldn't stop them from cooling.

Have you tried setting the PUMP in the Corsair Link to PERFORMANCE?

check how warm the tubes are to see if the pump is actually moving water

The H440 has very restrictive panels. See how comparison compares between the coolers with the front and top panels removed.
