Hey so I'm new here and new to liquid cooled systems I just recently bought a Corsair H100i and a new case from raid max the viper GX my radiator had some slight issue with positioning but i got in in there and got it working and recieve a cpu fan error message but I choose to ignore it within my bios since all fans are working i also installed some additional fans not stock but my problem lie with my temps.

Before liquid cooling with purely air my temp were around 65 degrees Celsius idling my temps now with liquid cool are 45-50 degrees Celsius again JUST IDLING compared to some friends who have liquid cool with 120mm fans (half mine) they are pulling 5 degrees Celsius IDLING neither of which are OC so is my liquid cooling system defective I have not had it in but like 24 hours and im not seeing any drops in temps but a slight raise I also put rubber spacers between the back plate and the motherboard which was something I saw recommended by a lot of people I just don't know what I am doing wrong... please help

I doubt 5C is an accurate temperature, unless they live somewhere with a very low ambient temperature. Many motherboards and processors have a hard time reporting idle temperatures and only get near accurate when they are reporting load temperatures. It is hard to determine if you indeed have an issue when you only list idle temps, don't tell us what ambient temperatures are, don't give us your system specs and pretty much don't tell us anything except that you switch from air cooling to an AIO water unit that has dropped your idle temps by 15 to 20 degrees.

My ambient temperature is about 75 within my house Im using a 3.4Ghz I7 LGA 1366 cpu and no he is actually get 5 Celsius as his idle temps and his temps under load goes up to about 15 where as mine goes up to about 55-60 celsius under load and if you true need the rest of my specs I can get them but it should not effect my liquid cooling CPU

55-60C for an i7 is not high and is fine, his temps seem to be incorrect as 15c is 59F and you cannot get 16F lower than ambient with a water cooler. So the problem here seems to be that your friend's computer is reporting incorrect temperatures.

also remember that the H100i is a mediocre cooler, not much better than most $50 air coolers, if better at all. Some Noctua air coolers will perform better. If you are really concerned you can attempt to reseat the block.

75 Fahrenheit is my ambient I do not know what his ambient is because he has sent me screen shots of his HW Monitor giving him a solid 5 Celsius I have not been to his house so I cant say what his is but from everything I have read my temps would be fine if I was OC my system but since im not using any OC at all my temps should be low 30's Celsius which makes me wonder why my system is running a stable 40-45 Celsius I mean maybe this is my naive sense that liquid cooling would give me much lower temps

Like I said, those numbers do not seem to be ridiculously high or indicative of a problem however, if you feel that they are too high you can try to reseat the block on the CPU and if you are not doing so already, setup the radiator with push/pull fans. Also your case setup can make a difference as hot air being pulled into the radiator will be less helpful than cooler air. Again, I don't care if your friend sent you screen shots, his temperatures are either wrong or his ambient is <59F

Well thank you for the information I do find this extremly helpful and definitely relieve some of the weight off my shoulders know my system is working :)
