Bad temps on H100i running out of ideas

[Beach]

I bought a H100i about two weeks ago and have had issues with it. I have been reading the forums for the past two weeks seeing if i can find a solution to the problem but nothing seems to work. Thinking about RMA'ing it pretty soon if I can't figure it out wondering if anyone has any tips for me. I came from a hyper 212+ on an asus p8p67 pro w/ 2500k OC'd to 4.6 w/ a 1.4 OC. On the hyper 212+ i was getting 28 idle and 75 under IBT. Now w/ the h100i I get about 35 Idle and a 85 under IBT. I have it in a R4 case on the top exhaust with both side panels of the case off so cold air isn't an issue. In corsair link it does register the pump at 2200RPM. I have tried everything:

 

back bracket is on orientated correctly

tried reseating waterblock multiple times and different TIM method w/ MX-4

Put the washers on the backplate as people have said that has helped w/ the excess slack

 

Tried it with cougar cf-12hp fans(worse performance)

 

anyone got any other suggestions before I RMA it

push or pull configuration?

 

try a push configuration... I bought a HAF XB case in which if I keep my H100i it mounts the rad to the front of the case in a down-flow position... meaning the spent hot water would go in to the top of the rad and the cool fluid would return to the cpu from the bottom of the rad... same principal as an automotive radiator in your car.

Push or Pull will not result in 10 degree worst performance than a air cooler. In my opinion, it has to be the mounting.

if they are bringing hot air from inside the case and exhausting it out the top thru the rad it may increase temps.

 

personally I'd never consider pull, I would only set up a push configuration and not both... but that's just me.

 

push-pull at these radiator depths are meaningless and just for show.

The idle temps are always higher compare to an air cooler. Im running the new Silverstone TD-02, my 2600k overclocked @ 4.6ghz with 1.43v. My idle temps are like 38C. I had the H100i couple days before this one, and the idle temps were the same. I'm running push + pull configuration (pushing air from inside the case through the Rad to outside). I know I will get better temps if i do the other way which is Intake air from outside through the Rad. But Im sure the difference would only be around 3C or so diff, so the'rs no point in doing it for more dust.

Sorry can't believe i forgot to mention its in a push configurations. I don't think it is pushing hot air at all as both of those sides are off the case at this point so no hot air buildup. I'll try again tommorow remounting it again to see if there is any improvement.

You might have mounted it wrong, the cooling head, my cpu was clean in the left lower corner, top right corner there was som thermal paste but it looked like it wasn't there anymore when i took the cooling head of. from the 2 remaing corners there was som thermal paste across my cpu so i might not have mounted the cooler right the first time.

 

What i am trying to say i might not have mounted it 100% perfectly and there for gotten higher temperatures then i should have, i you could also have had this problem.

Just put the stock fans back on and reseated the water block. Still getting high 70's in IBT.

 

Just curious when you guys are doing your burn tests how much does the temperature on the pump goes up. mine goes up about 5 degrees.

At 1.4v on my ivb the temp slowly rises until it overheats. You should be happy with those temps.
