Just got a H240X2 and working fine, but cold air / fans

post #1 of 19
Thread Starter 
For me, getting a new cooler, and all that, is totally new for me. That's why I got a newbie question, so I can understand what is happening.

Today I installed the H240X2 in my case @ Z97 MSI Krait and it's working fine. Some tuners at this forum told me I got too much thermal paste on the CPU.
Is this the reason why there is not coming really hot air from the fans? It's not feeling warm or anything. But the CPU was around 90C @ 1,29V 4,8Ghz in Prime 27.7 (i7 4790K). I think the fans should get the heat out, but it's not heat.

Any tips / suggestions?

That is not an unusual temperature for prime95

Allright, thanks. Do you think better thermal paste apply will lower the temperature? And how much thermal compound should I apply on the CPU? Core 4 is 12C lower then core 2 + 3. Maybe delid will help too?

But I wonder - that's why I made this topic mainly - should the radiotorfans put out hot air when the CPU is 90C?

Your radiator will eventually put out hot air once the water warms up. But the water takes a while to warm up.

Well from what I understand, with the way a closed loop works, it doesn't take all the heat from the CPU in one go and remove it all from the radiator either. It takes several passes of the liquid to cool a component. Your water will gradually heat up more and more until it reaches a stable equilibrium of being cooled as fast as you heat it up. In my PC, when I had 6 radiator fans running at like 200RPM, my 290 would heat the water to like 40C, but it would take maybe an hour. The whole time the GPU wasn't going over 65C as far as I saw.

So, I would imagine if you aren't running at those temps for around 20 mins, you wouldn't notice warm air.

If you have a core that is more than 10C difference from another core, I would try a repaste. Or perhaps the block isn't tightened down properly? Make sure you tighten the screws in a star pattern. For example: Top Left, Bottom Right, Top Right, Bottom Left - repeat.

Much better TL;DR for what I said lol

Will Coollaboratory Liquid Ultra work to use between the CPU and waterblock? And if lapped? Mine is not yet. If not, what did work for you?

Thanks for the help! Well, nothing wrong here then. smile.gif
I tried to tighten the scrwes in a star pattern, but it's kinda hard tho. I mean, the screws could move 10mm each in the bracket, so it's not easy to put them in place, before tighten the waterblock to the CPU.

Soon the CPU will be delid, and I will buy some paste, like Liquid Ultra for that. And I'm not sure what to put between the CPU and waterblock yet.

TIM is one of those instance's when less is more to a point. Most will say a pea size will do, nothing more, nothing less. I'm running that same chip with the same cooler at 5ghz and idle in the mid 30's and don't see anything over 55 when I game.

Wow, really. What Voltage are you using and is your CPU delid? Also, what thermal paste / liquid are you using?

It is a delidded silicon lottery edition, I'll look on the volts when I get in tonight. CLU between the cover and die, and PK1 between cover and waterblock; http://www.newegg.com/Product/Product.aspx?Item=9SIA0AJ2FH0504
