How to check the pump speed of corsair H80

Use your ears.

good joke the tech support team is telling me to check whether the pump speed is 2000rpm
..the problem is my stock i5 3570k is 40c all cores at idle my room temp is 26c

You can't, unless you buy the Corsair Link.

I'm serious, use your ears and listen for the pump.

That's why they now have the H80i and H100i with Link built in.

the pump is running i can feel it by touching my hands.can u solve my problem the things that i checked are
whether the screws are evenly tightned
whether the stock fans are in right position
but i have one doubt .after fitting the cooler to my processor again i removed the cooler to check whether the cooler sits properly so some amount of thermal paste got stuck with the processor then i again fitted the cooler is this may be a problem?

what is the actual problem?

is the cpu overheating?

not overheating it's the problem of high temp.i'm running a stock speed i5 3570k all core shows 40c at idle with this temp can i overclock to 4.5ghz?here are the readings at idle http://s17.postimage.org/63bf44unj/cpu.png i expected 26-30c on all cores as my room temp is 26c

You're not going to get those temperatures on a closed loop. Those temperatures are only achievable on real watercooling. What are load temps?

max temp is 60c on full load.my question is with this temp can i overclock my cpu to 4.5ghz safetly

You need to try, otherwise you won't know.

First learn to overclock the 3570k.

This ^

Is a problem. And could easily cause it to overheat. Anytime you take a cooler off you should clean both the heatsink and chip (lint free cloth like a coffee filter and some isopropyl alcohol) make sure no grease is on the mobo, etc. Reapply the thermal paste and re seat. Then check temps and loads.

so what thermal paste should i use and can i use tissue paper for cleaning the thermal paste

No don't use tissue paper that's bad news. Make sure you have something that is "lint/static free" A coffee filter is perfect if you don't have anything else. Any thermal paste will work if you have some on hand. If you need to buy some Arctic makes good paste.

*edit* Keep in mind Ivy bridge runs a little hotter then most. This just might improve your temps a little more and give you some more room for your higher OC that your looking to achieve.

how much should i get at idle with 26c as my room temp ?

at idle to be honest i don't know. Just haven't messed with the chip myself. But from a lot of the stuff ive read/seen at full load you shouldn't get over 70C with an evo 212 and I bet your cooler should be close the same performance. Give or take a few degrees both ways.

The absolute max temp for a 3570k is 105c. That's when bad things happen, so even if you broke 70c your fine. But most would like to stay under that.

My best guess idle is around 32-36c. Just a guess thou.

Idle means your CPU isn't stressed.

i'm using an another core2duo E8400 system at stock speeds with stock cooler the temp at max didn't even rise to 50c.than what is the advantage of using watercooler over air cooler if cooler master hyper 212 evo costs less than H80 but performs equal to it.

It isnt a real watercooling unit. That would be your answer.  

noctua nhd14 was not available on my area so i thought h80 might help but i'm dissapointed

It's not a bad cooler, It's not a amazing cooler either. IMO it's doing just about what it's suppose to. You have to keep in mind that IVY is just a hotter cpu then anything else.

Muffins right thou, it's not water-cooling like the enthusiasts think about it. (which costs a lot  ) But you'll still get good performance out of it and your chip.

Also keep in mind... 4.2 Ivy = 4.5 Sandy. So your little dual core is prolly something equal to like 5.0 ghz at a 4.2 ivy clock. The chip is just a lot more efficient

is this specs good enough for 1600x900 gaming
intel core2duo 3ghz
4gb dddr2 800mhz ram
amd 6570 1gb ddr3
will i be able to play games like bf3 with medium settings.is this processor is still a good enough one?
