Hi guys, I have ported my H100 which has been doing a fantastic job keeping temperatures below 70 on a 4.6Ghz OC'ed 2600k, to a 4770k. 4770k initially had the Intel liquid cooler (some intel rebranded cooling system) which had half of the radiator and only 1 fan. H100 has twice the size radiator and 2 fans. I replaced the Intel cooler because at a 4.5ghz overclock the cores were hitting 80 degrees and I thought I could do better with the Corsair H100. I installed the H100 and even at the high performance mode with all the stock fans going at top speed, my temperatures did not drop. I am still at the 79-81 degree range.

Online reviews show H100 being about 10 degrees cooler than the Intel system but I cant achieve it.
Question is why?

1- I used artic silver thermal paste, but cleaned the surfaces using only alcohol, could be a seating, or the thermal paste usage problem? I am thinking about this because although I do not have a push pull system (just push), when I touch the radiator and the hoses they are cool to touch while the cpu is burning at 80 degrees. If the cooling system was having trouble cooling the CPU down, then it should be warm/hot to touch and not have enough surface area or quality fans to remove the heat away from the radiator.

2-Intel is actually just as good as H100?

3-Something is wrong with my H100?
 
Hey there Andyk5!

So regarding your 4770k, you said that you have it overclocked to 4.5ghz, but what is the voltage at?

2 fans in push should be more than enough for what you are doing with your h100.

It might be a contact problem, but I would like to know about the voltage you are running before I jump to any conclusions.

The Intel is not just as good as the H100, but it may be that your 4770k can achieve the same overclock with both.

I'd start with the voltage and the contact before I would look at the H100 as defective.
 
Hey man, thanks for the reply,

I bought the systems from someone as pre built and started incorparating parts from my older i72600k system. That is where the h100 came from.

As far as the voltage, I have no idea since I did not look when I was overclocking,I just raised the multiplier, trying to make it crash on prime 95 while checking temps to see where the voltage was going to be inefficient. I went up to 4.5 on the multiplier and it seems to run fine, however I guess I should have not guessed that the voltage may have been already turned way up by the previous owner.... maybe I should reset the bios and start from the beginning.

I am also thinking maybe artic silver is taking its sweet time to cure.
 
A program like Core Temp should report the VID (Voltage) as well as the temperatures of each core. That might be an easy place to start.

I wouldn't suspect the cure time of the Arctic Silver to be the culprit here.

I'm sure we'll get to the bottom of it, and it may just need a re-installation.

Let me know about the voltage situation as you figure it out!
 
Ok, I just put everything to Auto on this Gigabyte g1 motherboard, the multiplier is set at 35.
Voltage settings etc are all auto.

When first started Prime 95 it was pulling 1.16volts with a multiplier of 39 @90 degrees, as the temps creeped up towards 100, the multipler and voltage started to come down and I took this snippet as it was at @38. Temp settings on the H100 is the medium setting, and increasing the fan speed does not seem to lower the temperatures.




and this is idle

 
It needed to be reseated, I did not even re apply thermapaste and temperatures are stable 59-67 under full load, even idle temperatures are done by 5 degrees.

Now it is time to crank up the voltage and multipliers lol
