H100I cooling problems

[Chacha]

Hi guys , for my CPU i've a Corsair H100I, and i've check some spech reviews and they say that it have about 28 °C in idle and 50/60 °C under load. But mine goes at about 40 °C on idle and sometimes 70/80 °C under load and i can't understand why. the CPU isn't even overclocked. I left the stock thermal paste, but i've got at home a stick of Artic MX-4, should i change it? Can someone help me ? thanks very much

Do keep in mind ambient room temperatures do effect your overall PC temp.

Hey, as @MyInnerFred said. Ambient temps do affect component temps. How is the air flow in your case? Perhaps the air flow isn't as efficient and there isn't enough cool air coming into the case??

I believe it was stated positive air pressure into the case gets you better cooling results.

Yup and keeps most of that pesky dust away

The ambient temperature is about 12-14 °C, so ins't to much . @MyInnerFred How i create positive pressure?, my current setup is 1 120 exaust in the back, 1 140 intake in the front 1 120 intake on the side pannel and the 2 120 for the H100I exaust on the top

[Enderman]

what fans are you using on the H100i?

are they stock?

i would suggest replacing them to something more silent and pressure optimised line an NF F12

also some CPUs get hotter than others, depending on their heatsink

Wow them ambient temps are low 

 

Generally, the more intake fans vs the exhaust fans will create positive pressure. You could turn your rear fan to an intake and have it all exhaust out the top. Top exhaust works best, I think. Since that hot air rises and naturally the air would go to the top. If all fans from below take cool air in, it will push its way up to the top and the top fans will exhaust the heat  :lol:

basically what he said^

@Enderman As CPU i've a I5 4670K and the fans are Corsair SP120 HPerformance, not the stock fans. Ok i'll try to do this, hope the best . Thanks Guys . Only a thing @Elven if i put all intake and the only exhaust fans are the top fans of the H100I for cooling the liquid i'll use hotter air, it can reduce the performance?

I would think that it wouldn't make a difference. The exhaust fans will work with what air is inside the case. As long as the intakes provide plenty of ventilation (more intakes will have positive pressure and more cool air inside).

I would try re-seating the block with new paste. Your temps don't sound right to me even if you don't have the most effecient case flow setup.

I only have my two stock H100 fans setup as a push and my temps idle at 22C and max load of 57C according to HWmonitor.

 

Give it a shot!

@Steemax Infact they don't sound good neither to me, i've tryed a stress test and it almost reached 100 °C, i think i'm going to change the thermal paste

Yeah sounds like theirs an issue with the install. No way it should reach a 100c unless you have it OC'd and the voltage set to 1.4v

So give it a shot and let me know if that remedies the issue.

pay attention to how well the thermal paste has spread, if the backplate and bolts are very loose you might want to put something between them so the waterbock sits better on the cpu, might be worth taking a look at this thread.

Your block isn't seated properly

 

Unmount and reseat it 

[n0mahd]

And check if your backplate is the right way. And not switched the other way around.

[Chacha]

I've changed the thermal paste but the results are the same, @tobben what can i put beetwen the backplate and the mobo to make it sit well?

on my motherboard the backplate and bolts were pretty loose and wobbling around, the waterblock barely made any contact with the cpu at all so i put some small rubber o-rings between the motherboard and the backplate, like this.

 

but be careful when you are tightening down the waterblock so you don't put too much pressure on the motherboard, or bend it for that matter.

Thank you , as motherboard i've an MSI so i think the thigtness is like yours (that as i see from the picture is an MSi) which dimension are the rings and where i can buy them?

it depends abit on the case and motherboard, it probably isn't the same but you should be able to notice if the thermal paste spreads properly, or if the backplate is fairly loose after you screw down the standoffs, i got this kit from ebay. http://www.ebay.com/itm/350721494081?ru=http%3A%2F%2Fwww.ebay.com%2Fsch%2Fi.html%3F_sacat%3D0%26_from%3DR40%26_nkw%3D350721494081%26_rdc%3D1

 

i'm not absolutely 100% certain, but i think the ones i used were the 4,5x2 mm ones, again, careful when you tighten that waterblock .

I don't know what to do, i've put the rubber rings, replaced the thermal paste but still temperature doesn't go down, instead it increase!! if the waterblock is too thigt what happens? I'm desperate

 

Every time i unscrew the waterblock i have to replace the thermal paste?

well yes, it's also very important to get it as clean as you possibly can before applying new thermal paste, you want to clean it every time to avoid air bubbles and whatnot getting trapped between the surfaces with the old uneven thermal paste that has been pulled apart. 

 

how much thermal paste are you using? you really don't need much, you want the layer to be as thin as possible while providing decent coverage, there shouldn't be alot of side effects from over tightening except for the risk of damaging your motherboard, the copper plate on the waterblock could creep together and reduce coverage if tightening to the extreme. If the waterblock is sitting snug and tight on the cpu as it is supposed to with the proper amount of thermal paste there is not alot you can do, your temperatures shouldn't be that high, are you sure you put the rubber rings on the right side and mounted everything properly? could also get a program like cpu-z or check in bios what voltage your cpu is running on.

Yes i put the rubber rings on the back support for the block, i've put two of them because the wher thinner than yours, as you have done in your image, for the thermal paste i've put a line in the middle of the cpu. Tomorrow i dismount all and i try from the begin :wacko:  and let see.

 

the cpu isn't overclocked, so it should run with basic voltage and clock. I changed the stock fan with the Corsair SP120 High performance, this  should not create problems right?

while it SHOULD be running at stock i wouldn't take that for granted, i have seen motherboards messing with the voltage in the past, might be worth atleast checking even if the chances are 99,5% that it's running at it should, you changing out the fans should be perfectly fine as long as you made sure you got the fans in the right orientation and not fighting to blow air on eachother .

 

im not sure how big the haswell cpus are.. as for me i just put a tiny dot in the middle, the 3770k is very small, having a line might be abit excessive, but it's probably fine as long as it's thin, i prefer a dot as the paste spreads evenly, might not spread as well as it would with a regular tower heatsink though.
