Hot cpu and laggy in bios

I just put a PC together and am have an odd issue. I don't get any errors but in bios it is really laggy and the cpu gets in the mid 70's. I checked the settings in bios and everything looks Ok, default settings. I thought it was the board so I grabbed another board but had the same issue. I have 4 sticks of ram that I tested in another system I also tested the cpu. I must have missed something but I have been fighting with this for a couple hours so thought I would post this and have a beer. Any help would be awesome. 

check your cpu cooler,something isnt right on your cooling

 

I am using an H100i I have seated it twice and it is exhausting hot air. 

are you using good thermal paste? 

Is your cooler ON and the pump functioning?

Arctic silver 5. I left it for about ten minutes and it booted to Windows. I used a drive it was already installed on. I ran some tests and it seemed to run fine, turned it off and now post just loops. It will start to boot then restart. I think tomorrow I will just pull the build apart and rebuild and see what happens. 

Is the water moving in your cooler? The pump could have failed. Do you hear the pump working? If you wrap your hand around the tubing, can you feel the vibration from water moving around?

Yes I could feel water moving. Once I got into windows I monitored temps and they were really nice. Low to mid 30's.

try to update your bios..

Updating the bios can be dangerous on an unstable system. Try switching your current cooler for the stock. See what happens with temps. Instability I would think ram first but temps are worrying. Though my 4770k run at 60 degrees in bios.

Remove all but one of your sticks before you try the cooler. See if it runs better in the bios. If not, switch ram untill you ether find it running stable or you dont have any more sticks of ram. If your running haswell, The CPU can run cool with a bad cooler on idle due to low clock and voltage. Switch the CPU cooler to see if it makes a difference and make sure it seats properly!

If all else fails, run some air conditioning or do this when its cool and try a bios update. 

Alright everyone thanks for the help but it turns out I am an idiot. I didn't know doing this would cause this issue but it did. So i did the test boot out of the case and it booted fine put it in the case and that's when things ran weird. Turns out I had put a USB Bluetooth in one of the USB ports on the case so I wouldn't lose it and forgot it was there. and that's all it took. I pulled the USB Bluetooth out and everything is running smoothly.
