Temps went up after cleaning.

I have a large case, Coolermaster ATCS 840 with a Corsair H100 cooler that uses 4 fans in a push/pull configuration. Temps were at 45°C at idle, and 75°C under full load (video transcoding). Today I decided to clean the inside and change the direction the push/pull was blowing. I thought my temps (45/75) were too high and the cooler direction was blowing out. The Corsair radiator was very dirty, so I cleaned that and switched the direction of the 4 fans to blow in. My temps went to 65°C at idle to 86°C under load. Then I decided to replace the thermal paste since it has been about 3 years since I built this. Did that, and the temps are now 50/80. I switched the fans back so they are blowing out again and that did not change the temps. Any idea what is going on?
By the way, about 2 months ago I added a fan controller and an exhaust fan at the rear of the case. The fan is adjustable up to 182 CFM. It is very loud at full throttle, but it does not even change the temps one degree.
 
Those are pretty high at idle. Is the pump plugged in for the h100, or possibly dead? Wouldn't matter if your fans are working at 100% if the pump isn't flowing water correctly.
 
That might actually be a good explanation. I might have dislodged something by moving it around.
How would I check this since it is a sealed system? And how would I check the pump? It's not easy as all the case fans make it impossible to hear if it's running.
 
Can you squeeze the coolant lines? The less pump flow the higher the pressure. If the lines are hard as rock then I'd say the pump is stopped up.

It would be the opposite actually. As you squeeze the line, you increase the resistance to flow and pressure increases as the water tries to force its way through the blockage.

What you are thinking of is when there is flowing water in standing water (or air), the flowing water is at a lower pressure compared to the standing water/air. This is not applicable when the water is enclosed as in a CLC.
 
You could pull the power for the pump to validate any variation in the temperatures. I am going to guess that they do not change.
 
I pulled the power to the pump. The temps shot up and I had to shut it down. I hadn't noticed before, but the pump was making a pretty loud noise, so it's probably failing. I called Corsair and they have a new one coming to me - since it was in warranty and I did have the receipt. Since they don't make the H100 any more, they are sending an H100i.

Question: Is there a more efficient cooler similar to the H100i (and at the same price point) ?
 
NZXT Krakens would be your other choice. But top end CLCs will perform similarly to top end air.
 
What are the top end air systems that would be equivalent to the H100i?

Top air coolers are better than H100i .. most by several degrees and even more when H100i fans are slowed down to same noise level as top air. This was discussed on a thread here just over a week ago.

Here is a list of some of the top cooler sizes and clearances. Some are better than others, but all are within 5c of each other.

Top air coolers are better than H100i .. most by several degrees and even more when H100i fans are slowed down to same noise level as top air. This was discussed on a thread here just over a week ago.

Agreed. That said, the H100i will be an improvement over the H100, if only for the reason that they changed the tubing between the two models. The H100 used this narrow, corrugated tubing, that was less flexible than that on the H100.

Personally, I'm a little wary about hanging all that metal off a vertically mounted motherboard, which is part of the reason why both my new cases have horizontally mounted motherboards. If that is a non-issue, and you have the space, and you don't mind the aesthetic, I would probably just grab an NH-D15.

Honestly the weight and size of big air coolers is not a problem. Almost everyone I know is using them and I know of nobody who has had any problems. Sure, if you knock it off the desk or drop in down the stairs something will probably break, but that's true of any system.

I'm using the NH-D15 .. as well as Cryorig R1 Ultimate, TRUE Spirit 140 Power, Archon IB-E X2, PH-TC14PE and Silver Arrow IB-E. It really isn't any better than others. Only reason it is a couple degrees cooler is the supplied NF-A15 1500rpm fans are faster than most other coolers use .. and the only way to get them is in a cooler package. The retail NF-A-15 is 1200rpm. Why Noctua has a 1200rpm and 1500rpom versions with same model number boggles the mind, but that is what it is.

An interesting bit of info is the NF-A15 and NF-A14 have same blade design and almost identical performance as Thermalright TY-140, TY-143 and TY-147 fans at same speed.

Just to add closure to this thread. I sent in my H100 and got the H100i replacement today. It is all installed now and I didn't realize how noisy the pump was on the defective H100. The new unit is much quieter and the temps are about 39°C at idle, and 59°C at full load.
