So ive had my 4790k for just over a year and i used to be hitting idle temps of around 25-30 a few months back. Check them today and after booting the PC they are at 40 and idle at around 45. Not liking this as my idle temps as i have a H100i which was cooling them fine a few months back.

V-CORE 1.185
 
At this time of year they should be low because at this rate if the temps don't go down they will be hitting the 50's in summer idle.
 
The Heat-sink? No i haven't, have been needing to use my PC all day and not had time to look at it. I don't think it will need new thermal paste as its only been a year and i used the one that came on the h100i its self. Don't want to put anymore one in case it starts insulating the CPU rather than transferring heat

Have you checked to see if there are any processes running in the background which are adding the the CPU temps?

I noticed the other day my idle temps had rose quite a bit & found a mediaplayer process using 20% CPU all the time.

Nope no processors using CPU much, all on '0' so cant be that
 
i have not updated my bios for around a year now, don't generally like doing it. Don't think it would help i they was fine a bit back.
 
Here are my Temps

Yeah but no change

I believe it is, i will give the water pipes a tap and run the pc on its side for a bit later to get rid of air bubbles. If not i'm going to decrease my V-Core as i have no overclock. even though it is quite low anyway

just a thought.. when I had the H80i fitted to my gigabyte board there was a bit of slack when tightened up. I ended out fitting a few rubber washers between the motherboard and back plate to hold the cpu block/pump tight to the cpu.

can you try running the machine with the side off and apply some gentle pressure on the cpu block to see if this may be youre problem.

I know you said you have previously not had a problem but just with you saying you had a patch of thermal paste that looked as if it had not made contact to the cpu Im wondering if this may be the issue

I will try this later when i have the time. I will let you know what happens:)
 
Nope no change after applying pressure for a few minutes and the backplate is tight so i don't know, any more ideas. When rendering video it goes to 60c but idle its around 50c now and i don't like these high idle temps at all as i used to get them to be 30 max idle
 
They are 50 after boot, been like this two days have not rendered for 3 days but did a benchmark test it is maxed at 60, trying to update bios now but gigabyte bios are a pain, I will feedback after
 
For the h100i I only think the pump is working because the corsair link software, I can I physically make sure it's working, obviously it's a water hybrid. What should I be able to do to test if it's working

Sounds like your CPU aint idling, something must be running in the background, your load temps while rendering are only 10 degrees hotter which makes me think it aint going idle. Hit ctrl+alt+del start task manager and performance tab and check its actually going to 0% cpu load. Mine flicks between 0-1% when im idle.

It's like spiking from 0-7, but I'm staying to wonder if it could be my pump not working. I can't hear any pump like noises but I wouldn't know what to listen for. What can I feel for on the pump to confirm if it is working or not?

After uodating my bios there is still no improvement. I will post an image of my coy usage tomorrow when idle but could not see anything using lots of cpu just all on 0 really
 
The temps go to around 70c and 60c when rendering which is good.

I think the vcore is locked but wouldn't know if it was?

Would you know how or where I can check the thermal settings?

I don't feel any vibrations or here any pumping
