I'm going to be as detailed as I can here but I have:

-i7 4790k Overclocked @ 4.4 GHz, 1.250
-Corsair h100 i mounted on the top of case with the fans inside and the radiator in between the fans and the top of the case.

I recently purchased the Corsair h100 a few hours ago and installed it properly and started overclocking my CPU.

My CPU runs on full load, that is with Prime 95, at about 99 degrees Celsius. Is this normal for this overclock? I'm only overclocking from 4 to 4.4 GHz using 1.250 of voltage. Is there something wrong with my radiator not getting enough cooling? Are the temperatures for the Haswells okay to be this high for this type of water cooling system?This is supposed to be one of the best water coolers on the market and I feel like I'm doing something wrong. I'm going to include a picture of it for more detail.

yes mate the address where temp data is stored is the same across all the i5 range. so there is no need to update the software for new cpu's
where as speed fan relies on addresses...

How hot are the pipes leading from the pump to the radiator? One should be significantly hotter than the other, especially if you get 99C. That is way too hot.

Also press on the pump/heatsink and see if the additional pressure yields an immediate reduction in temperature.

Can you feel warmish air moving out from the radiator? I'm betting there is an issue with your installation. Either defect or incorrect.

Just as an update, I reapplied thermal paste twice and they looked really good on the CPU when I checked.

As for feeling the tubes, they were just both the same temperature to me, more colder than hot actually.

I pressed on the pump and it made no temperature difference even running Prime 95.

Feeling the other side of the radiator, there is really cool air coming from it, but it is confusing me because simultaneously reads 100 degrees Celsius on CPUID.

thats a 4.4ghz turbo cpu so you shouldnt need any more than stock volts to get it to 4.4 on an oc with turbo off.
so drop the core volts to 1.1350.(or stock for your motherboard and the cpu should run fine)
this will drop your temps a fair bit if you havent damaged the cpu already with excessive heat...
run real temp on your system to see what the tjmax is you want to stay under 75% of that number or the cpu will start throttling. if it ever reaches the tjmax the system will shut down (hopefully without damage)

also listen to the pump on the cooler it sounds like it may be damaged if the temps of the inflow and outflow are similar. as said they should be quite different with the cpu running that that temp.
(take a screw driver and press it up against the pump and put your ear directly on the handle. you should hear the pump spinning. if you hear nothing but mild vibration then assume the pump is dead.

I dropped the voltage down to that but it crashed as soon as I opened up Prime 95. My question is why is my CPU temp so high? What could it possibly be? The temperatures are definitely not supposed to be this high with this sort of hardware.

Another thing to note is that the second I stop the test, temperatures come back down to 30-40. The split second I start it, it shoots back up to 99.

speed fan is hit and miss with some cpu's it will often read the wrong sensor or worse read the rite sensor but give a false output.
cpuid can do the same especialy when you dont have the motherboard nfo installed that helps windows detect the correct hardware.

my i7 shows 40's on speed fan but if i drop the cpu multi to 19 and run any kind of oc the temp speedfan registers is 10'c below what it actually is.
use real temp/ coretemp/hwmonitor they tend to give a more reliable result.

Sorry to go OT here, but I have a question. There is another recommendation on this thread for RealTemp. If I read the linked download page for RealTemp, there has been no updates since Sandy Bridge CPUs (around 2011-2012? Does it still give accurate and reliable readings on newer processors? Inquiring minds want to know. :)

Overvoltaged 1,3-1,35vcore 4790K runs with NH-D15 up to 80°C, sometimes 85°C, with TurboBoost 4,4 GHz on all cores.

Do modify Your settings in bios, don't let it go over 1,15-1,2vcore, 4790K doesn't need more for stock settins.

Now I'm running Prime up to 59-62°C after hours of testing, with 1,2 vcore and all four cores on 4,2 GHz, and with Aida64 55-58°C all four cores 4 GHz, at 1,15 vcore.

where as speed fan relies on addresses supplied by the motherboard for some hardware configs and is why it can give erroneous readings.
