Is my system Air locked?

[JazmaN]

I'm currently using an Antec Kuhler H20 920, I've been using it since christmas, and ive noticed over this past month that my CPU temps when idling is around 45-50*c, where as when i first started using it i was in the range of 32-38*c. A friend suggested that it could have become air locked, or have air bubbles, but theres no way to know for sure as the pipes aren't transparent

Is there a way to find out? I've been considering switching back to air cooling for a bit as i don't like that temp.

EDIT: I don't think it is because of the ambient temp and the hot weather we have had in england these past weeks, as my room is usually fairly cool

I agree with the idle temperature being a little high, after a few google searches there have been quite a few RMAs due to the pump getting air locked so it's definitely a possibility, what is the warranty on the cooler?

I doubt it would of all of a sudden gotten airlocked unless you move it about alot and somehow got the air from the free space in rad into the pump somehow. Its the ambient temps mate no doubt in my mind. i have seen a huge change in my temps of late as well.

clean out the rad .. remove the fans and vacuum it..

strange, i use to get alot better temps than that with the 620 they do

yeah she could be getting clogged with dust clean it out and see but you got it in december cold temps its now alot warmer outside even if you keep the room cool it still creeps up. I run my ac at 25c (77f) for when I am at home but my temps hover at 39c idle with 700mm of 60mm thick rads in push pull

but i'm thinking its my gpu's dumping extra heat into my case as the top 420mm rad is exhaust its using the cases heated air for cooling. Later tonight after i return my lil ones to their mum I'm going to make the 420mm rad intake air and see what difference it makes. If it lowers the temps then I'll need to figure a way to dust filter the top of my Switch 810 I really need to get my gpu's under water but alas one is a reference design (easy to find a block) the other is non reference (no block option)
