New cpu high temps

I just got myself an i7 6700k and used my Corsair h100i V1 in this build which ment had to reapply thermal paste. My temps in idle hang around 25-30 then boosts up to the 40's then right back down the the 25-30 range. I'm new to Intel so is this normal?

Also a side question I have a front mounted aio, should it be intake or exhaust? It's intake ATM.

  1. Completely normal. Front radiator should be intake.

  2. Er...those are super cool temps. Not sure what you mean by high? If you mean that it occasionally ramps to 40, yes that's normal. There are always background processes, some you are aware or, some not. You can monitor this in your task manager if you wish to know what's ramping it up at the moment it's happening, but it's perfectly normal.
    Should be intake so you have it set up right.

  3. Also, if I may ask another question since I have somebody, I'm using an Asus strix z270f Mobo, when I go into bios and do the easy wizard and I choose gaming mode, the PC restarts when I'm logging into windows. Also I have ddr4 3000mhz ram, how do I use the full amount?

  4. I am not sure what gaming mode means, exactly but I'm assuming it is some sort of overclock? Check this. If yes, then it will restart you to apply it, that's normal.
    For memory turn on xmp in bios. It should give you the 3000mhz as a preset option so you just select it.

  5. Yeah it's like an overclock, but when after I apply it the PC restarts on its own, perhaps something with the voltage? Also oc is the only way to get full usage out of the ram right? Ocing is new to me

  6. As soon as you apply, the PC will restart, it has to, to apply different voltages/clocks. Unless you're saying it keeps restarting and won't boot up?
    If you bought 3000Mhz memory, you should turn it on, yes. If you were trying to clock your memory to some freq that it wasn't tested for, then you'd be safer reading in detail about it first before attempting. If it said 3000 when you were buying, then it's meant to go that high, just turn on xmp and select preset.

  7. I hit present xmp and after about 30 seconds in windows the PC restarts itself. It seems like some failsafe thing

  8. Okay so it stopped restarting on me. I have xnp on, I have access to the 3000mhz, but my idle temps range from 30-55 now. It just went up to 61, then right back down

  9. The higher temperatures are likely because of your overclocked CPU. Your temps are supposed to be higher with overclocking though I'm not sure what you OC'd it to and how much higher temps you can expect for whatever it is now. Post what your current cpu clock is. Someone might chime in on this who knows better what temp range you can expect from whatever particular freq you clocked it to.

  10. It was working fine last night, then I added a fan, took it out, and now my PC is in a boot loop. I've reseated the ram, set bios back to defualt multiple times, and reapplied thermal paste to cpu. I can't even get into windows, and if I do it restarts in 20 seconds. I tried to reinstall Windows but to reboots during that too. What do? It's driving me nuts!!

  11. Ok. You've reseated the ram (hopefully you've tried both the 1/3 slot combination and the 2/4 one to see which is giving you less trouble), re-mounted the cpu. Try clearing cmos. Various way to do this (https://www.lifewire.com/how-to-clear-cmos-2624545). I typically just take out the actual battery and put it back in after some time. Then try restarting.

    So it seems to have been fixed, not sure what wrong where, hopefully it doesn't come back later either, but i switched to xmp profile 1, booted up normal and no reboot. I went back to bios and did the defualt and everything works. But everytime.i turn on my PC it goes into bios before windows. Do I need to update my bios? And with the whole reboot issue, if it starts happening again I'll let you know. I didn't have to do anything with the cmos.

  13. Er...check your boot sequence in bios and make sure it's set to boot to your hard disk first (or after usb/dvd drive at least).
