4 out of 5 eggsI think its is good

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: got my temps down by 5C from stock CPU cooler

Cons: I didn't like combined intel & amd backplate. had remove the motherboard to install back plate because I only needed AMD, and the intel arms got into way. would have been perfect if it was only AMD back plate.

the tubes are with spring action are no to my liking. makes it harder to install the pump.

instructions are ehhh..

Other Thoughts: It works! better than stock fan

it would have been nice it had arrive on time, came 5 business days after expected delivery day.

1 out of 5 eggsBuy anything else

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: Cooler Master's customer support, small unit

Cons: First of all, the fans would only run at 2400 RPM, and at idle keep it at 40+ degrees. I RMA'd it with cooler master and they sent the same unit back, 3 weeks later, without instructions this time. No surprise it still doesn't work, I'm going to return it to Newegg and getting a different brand.

Other Thoughts: Don't be drawn in by the low price tag, spend the extra money and get a decent cooler.

3 out of 5 eggsDecent Cooler

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: Easy to install, fan and cooler are quiet.

Cons: The tubing is corrugated and very difficult to use. The tubing sprung a leak after 6 months and caused damage to my power supply. However the tubing is 100% replaceable.

Other Thoughts: I would suggest replacing with flexible tubing upon purchase.

5 out of 5 eggsSeidon 120V works

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: Better than more expensive air-only solutions
Water acts as a sink to spread out the temperature peaks
Quiet. I can't hear the pump - only the fan.

Cons: Tubes are stiff
Couplings on CPU end do not rotate

Other Thoughts: My stock 4GHz i7-4790K would overheat running Prime95 with four cores. Replacing the stock cooler with this allows me to run *either* full speed on all cores, *or* overclock significantly (4.9GHz turbo). Not both. You need a higher capacity cooler for serious overclocking.

5 out of 5 eggsBest CPU for the masses

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: Cheep - coming in less expensive than more air based cooling options how can you doubt this?

Effective - In many tests its one of the most effective cooling options.

Easy to install (easier than those darn push pins thats for sure).

Still cannot handle a 4790k with the new synthetic tests (nothing can) It might keep you sub 90 C however... This is oddly a pro.

Quite oh is it.

Cons: Coarse grain on block (good for inexperienced installers as this is more forgiving with too much thermal paste). Adhesive on the block that you peel off.. What why i rather just clean then instal it than scrub to to be sure no adhesive stayed attached.

Other Thoughts: I just lapped the block as i always do, the the coarse grain didn't matter to me.

The pump house seems a bit weak. This is fixed in later models i noticed, but its fine.

1 out of 5 eggsdoesn't cut it

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: looks good

Cons: Not enough cooling.
A good heat sink will do alot better job than this thing.
Poor installation instructions.

Other Thoughts: I'm not sure if I installed this thing correctly, but I get better cooling from the heat sink I replaced it with.

5 out of 5 eggsCooler Master Seiden 120V

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: Smaller foot print over Zero Therm Butterfly heatsink. Dropped CPU temp 25 deg. F..at idle...When running Seti max CPU, all 6 cores, Temp. stayed @ 112 Deg's F, old cooler was 148 deg. Real Happy so far...Was remufactured, looked unused and brand new. Got this for 29.99 after rebate.. Great Deal

Cons: Some what tricky to get seated correctly. Make sure bolts center prior to tightening. Had to mount radiator overhead in my Cooler Master case, wouldn't fit rear. Still not a big deal to me.
